It explores the two basic aspects of the fluctuation theorems: i) Applicability in extreme situations with divergent entropy production, concluding that the fluctuation theorems remain valid under the notion of absolute irreversibility, and ii) utility in the investigation of classical enigmas in the framework of statistical physics, i.e., Gibbs and Loschmidt paradoxes. The book offers readers an overview of the research in fundamental statistical physics. Firstly it briefly but skillfully reviews the modern development of fluctuation theorems to found the key theme of the book. Secondly it concisely discusses historical issues of statistical physics in chronological order, along with the key literature in the field. They help readers easily follow the key developments in the fundamental research of statisticalphysics.

This work presents some essential techniques that constitute the modern strategy for computing scattering amplitudes. It begins with an introductory chapter to fill the gap between a standard QFT course and the latest developments in the field. The author then tackles the main bottleneck: the computation of the loop Feynman integrals. The most efficient technique for their computation is the method of the differential equations. This is discussed in detail, with a particular focus on the mathematical aspects involved in the derivation of the differential equations and their solution. Ample space is devoted to the special functions arising from the differential equations, to their analytic properties, and to the mathematical techniques which allow us to handle them systematically. The thesis also addresses the application of these techniques to a cutting-edge problem of importance for the physics programme of the Large Hadron Collider: five-particle amplitudes at two-looporder. It presents the first analytic results for complete two-loop five-particle amplitudes, in supersymmetric theories and QCD. The techniques discussed here open the door to precision phenomenology for processes of phenomenological interest, such as three-photon, three-jet, and di-photon + jet production.

This book is based on the analysis of canonical commutation relations (CCRs) and their possible deformations. In light of the recent interest on PT-quantum mechanics, the author presents a special deformed version of the CCRs, and discusses the consequences of this deformation both from a mathematical side, and for its possible applications to physics. These include the analysis of several non self-adjoint Hamiltonians, a novel view to the position and momentum operators, and a general approach to compute path integrals and transition probabilities using the so-called bi-coherent states. The book is meant for researchers and is also suited for advanced students. It can be used as a gentle introduction to some delicate aspects in functional analysis and in quantum mechanics for non self-adjoint observables.

Will artificial intelligence make scientific formulae redundant by eventually solving all current and future physical problems? The authors of this book would argue that there is still a vital role for humans to play in making sense of the laws of nature. To derive a formula one follows a series of steps, only the last of which is to check that the result is correct. The book is about unravelling this machinery.Mathematics is the 'queen of all sciences', but students encounter many obstacles in learning the subject: familiarization with the proofs of hundreds of theorems, mysterious symbols, and technical routines for which the usefulness is not obvious upfront. Learners could lose motivation, not seeing the wood for the trees.This two-volume book How to Derive a Formula is an attempt to engage learners by presenting mathematical methods in as simple terms as possible, with more of an emphasis on skills as opposed to technical knowledge. Based on intuition and common sense rather than mathematical rigour, it teaches students from scratch using pertinent examples, many taken from across the physical sciences to demonstrate the application of the methods taught.This book draws on humour and historical facts to provide an interesting new perspective on what a mathematics textbook could be. The two volumes are presented as an ascent to Everest. Volume 1 covered the necessary basics, taking readers from Base Camp to Camps 1 and 2. This volume moves readers from Camp 2 up to Camps 3 and 4, tackling more advanced methods for deriving formulae. Inevitably, Volume 2 requires readers to tackle more challenging terrain than was experienced in Volume 1 and so is targeted at more advanced students.

Supercritical pressure fluids have been exploited in many engineering fields, where binary mixtures are frequently encountered. This book focuses on the coupled heat and mass transfer in them, where the coupling comes from cross-diffusion effects (i.e., Soret and Dufour effects) and temperature-dependent boundary reactions. Under this configuration, three main topics are discussed: relaxation and diffusion problems, hydrodynamic stability, and convective heat and mass transfer. This book reports a series of new phenomena, novel mechanisms, and an innovative engineering design in hydrodynamics and transport phenomena of binary mixtures at supercritical pressures. This book covers not only current research progress but also basic knowledge and background. It is very friendly to readers new to this field, especially graduate students without a deep theoretical background.

This book describes the computational methods most frequently used to deal with the interaction of charged particles, notably electrons, with condensed matter. Both elastic and inelastic scattering phenomena are discussed, and methods for calculating the relevant cross sections are explained in a rigorous but simple way. It provides readers with all the information they need in order to write their own Monte Carlo code and to simulate the transport of fast particles in condensed matter. Many numerical and experimental examples are presented throughout the book.The updated and extended fourth edition features ab initio methods for calculating dielectric function and energy loss function. Non-relativistic partial wave expansion method for calculating the differential elastic scattering cross section is also included in this new edition. It represents a very useful introduction to the relativistic partial wave expansion method, i.e., to the Mott theory, already discussed inthe previous editions of this book. Further details about the effects of spin-polarization on the differential elastic scattering cross section are included in this new edition. The multiple reflection method is extended to the general case of a system composed of a set of layers of different materials and thicknesses. Analytical expressions are provided for calculating the backscattering coefficient of multilayers. New results are presented, notably about Monte Carlo simulations of reflection electron energy loss spectra and of the radial dose deposited along the track of ions impinging on materials.

Distant galaxies, dark matter, black holes - elusive, incomprehensible and inhospitable - these are the building blocks of modern physics. But where do we fit in this picture?'A delightful account of one of the deepest and most fascinating explorations going on today.' CARLO ROVELLI, AUTHOR OF WHITE HOLESFor centuries, we have separated mind from matter. While physicists have pursued a theory of 'everything' with single-minded purpose, the matter of the mind, of human consciousness, has been conveniently sidestepped and ignored - consigned to priests, philosophers and poets.With the ambition of Stephen Hawking, Carlo Rovelli and Brian Cox, Putting Ourselves Back in the Equation sets out a bold new vision for theoretical physics, unrestricted by sleek equations and neat formulations. Combining cutting-edge neuroscience with the latest in quantum mechanics, acclaimed writer Musser offers a new interpretation of human consciousness. From bizarre cognitive phenomena, like lucid dreaming and self-taught synaesthesia, to the latest technological developments in AI, Musser asks: what can physics teach us about what it means to be human?***'The renowned science writer George Musser has taken on one of our time's greatest issues: AI, how it works, and what makes it so powerful. This masterfully written book shows a surprising connection with theoretical physics.' MAX TEGMARK, AUTHOR OF LIFE 3.0'Musser is to be applauded for tackling both consciousness and the quantum realm... He joins a distinguished list of thinkers... Musser's book is readable and enthusiastic, packed with first-person anecdotes.' TLS'In this captivating book, George Musser takes us on a fascinating tour of the modern, surprising connections scientists discover between the cosmos and our inner world of consciousness.' MARIO LIVIO, AUTHOR OF THE GOLDEN RATIO

The "holy grail" of physics is quantum gravity, often called the theory of everything. But any scientific theory will be incomplete without the God of the Bible. Physicists claim the cosmos began with a big bang created from nothing. But the word nothing is meaningless in physics. Furthermore, the big bang is an impenetrable barrier to whatever preceded it. In addition, a finite cosmos cannot contain within itself an explanation for its own existence. To claim we are here by accident explains nothing and leads to a logical dead end.The cause of the universe is information in the form of mathematical laws left behind for science to discover. The fundamental properties of these laws have the same attributes as the Supreme Lawgiver of Genesis. An intelligible cosmos is unmistakable evidence the Creator is an Intelligent Mind. The Creator's Voice is a valid scientific theory confirming the truth of Genesis; God spoke the laws creating the universe out of nothing, creatio ex nihilo. The foundation of the universe is ethereal cosmic waves which interact according to the laws to create and sustain the illusion of reality we experience. Space, time, energy and matter are made from quantum information; nothing else is needed. By a process of elimination, God is the only possible explanation for everything we know.The human mind is evidence consciousness is endemic to the cosmos. Cosmic waves interact with the human mind in mysterious ways. The cosmos relates to humans more like a great Mind than a mindless machine. The god-like nature of the human mind is evidence; we are made imago Dei. Even if God is included in a scientific theory, it means little unless it can be shown God is a real Being, alive, present in the world and relevant to our lives.

This book gives its readers a unique opportunity to get acquainted with new aspects of the fruitful interactions between Analysis, Geometry, Quantum Mechanics and Number Theory. The present book contains a number of contributions by specialists in these areas as an homage to the memory of the mathematician Erik Balslev and, at the same time, advancing a fascinating interdisciplinary area still full of potential. Erik Balslev has made original and important contributions to several areas of Mathematics and its applications. He belongs to the founders of complex scaling, one of the most important methods in the mathematical and physical study of eigenvalues and resonances of Schrödinger operators, which has been very essential in advancing the solution of fundamental problems in Quantum Mechanics and related areas. He was also a pioneer in making available and developing spectral methods in the study of important problems in Analytic Number Theory.

The book is based on the author's PhD thesis, which deals with the concept of time in quantum gravity and its relevance for the physics of the early Universe. It presents a consistent and complete new relational formulation of quantum gravity (more specifically, of quantum mechanics models with diffeomorphism invariance), which is applied to potentially observable cosmological effects. The work provides answers to the following questions: How can the dynamics of quantum states of matter and geometry be defined in a diffeomorphism-invariant way? What is the relevant space of physical states and which operators act on it? How are the quantum states related to probabilities in the absence of a preferred time? The answers can provide a further part of the route to constructing a fundamental theory of quantum gravity. The book is well-suited to graduate students as well as professional researchers in the fields of general relativity and gravitation, cosmology, and quantum foundations.

The book shows how to develop the classical ideas of mathematics and physics - such as Newtonian force and inertia, the electromagnetic field, Euclidean geometry, complex numbers - without having to contradict these ideas. In this way one can explain the movements of the sun in our galaxy, the nuclear force, the X-rays, etc. All with only the classical mathematical and physical ideas.

This thesis is devoted to the systematic study of non-local theories that respect Lorentz invariance and are devoid of new, unphysical degrees of freedom. Such theories are attractive for phenomenological applications since they are mostly unconstrained by current experiments. Non-locality has played an increasingly important role in the physics of the last decades, appearing in effective actions in quantum field theory, and arising naturally in string theory and non-commutative geometry. It may even be a necessary ingredient for quantum theories of gravity. It is a feature of quantum entanglement, and may even solve the long-standing black hole information loss problem. "Non-locality" is a broad concept with many promising and fruitful applications in theoretical and mathematical physics. After a historical and pedagogical introduction into the concept of non-locality the author develops the notion of non-local Green functions to study various non-local weak-field problems in quantummechanics, quantum field theory, gravity, and quantum field theory in curved spacetime. This thesis fills a gap in the literature by providing a self-contained exploration of weak-field effects in non-local theories, thereby establishing a "non-local intuition" which may serve as a stepping stone for studies of the full, non-linear problem of non-locality.

This book introduces some new fractal dimension concepts to calculate the center point elevation from a 3X3 grid of actual topographic data. The implications are that there is an order to natural systems that has been newly identified.The material is presented in the form of a notebook study. The innovative fractal-type equations and ancillary concepts are conceptually concise. The calculation framework to obtain the center point values uses the fractal and ancillary equations to construct what are termed "positive" and "negative" criteria, as well as a "position locator." The solution for the center point elevation is arrived at via a mathematical sieve of these three factors.There are 13 example datasets that are evaluated. In each analysis, only the data from the relevant 3X3 region was used. The topographic data is from the Red Deer River area in Alberta, Canada. The accuracy of the calculated elevations compared to the actual center point data in a notable number of cases is truly amazing, to the point of being essentially perfect.However, there appear to be limitations to the technique that have yet to be explored to any significant extent. With only 13 datasets investigated, it is expected that additional refinements to the various criteria will be required. A full and final theory will have a more rigorous mathematical foundation to formalize the criteria.The book includes code snippets of the various calculation methods, so that others may enjoy their own explorations. Ideas for additional studies and improvements are suggested. Predicting values in non-center-point situations would be one of the next steps.The material is primarily designed to be accessible to individuals with an undergraduate background in mathematics, physics or the sciences.Applications to other types of data would appear to be possible.
