A Computational Introduction to Quantum Physics (1版)

類似書籍推薦給您

【簡介】 This concise textbook introduces an innovative computational approach to quantum mechanics. Over the course of this engaging and informal book, students are encouraged to take an active role in learning key concepts by working through practical exercises. The book equips readers with some basic methodology and a toolbox of scientific computing methods, so they can use code to simulate and directly visualize how quantum particles behave. The important foundational elements of the wave function and the Schrödinger equation are first introduced, then the text gradually builds up to advanced topics including relativistic, open, and non-Hermitian quantum physics. This book assumes familiarity with basic mathematics and numerical methods, and can be used to support a two-semester advanced undergraduate course. Source code and solutions for every book exercise involving numerical implementation are provided in Python and MATLAB(R), along with supplementary data. Additional problems are provided online for instructor use with locked solutions.

Steven Weinberg: A Life in Physics (1版)

類似書籍推薦給您

【簡介】 Steven Weinberg shares his candid thoughts, in his own words, on theoretical physics and cosmology, along with personal anecdotes and recollections of the people who helped shape his career. These memoirs of his life as a scientist and public figure cover his student days and early career, through the golden age of particle physics in the 1970s, his being awarded the Nobel prize, through to the end of the twentieth century. In addition to his research insights, Weinberg provides glimpses into his life in academia more broadly: dealing with the ’two-body problem’, tenure, international conference travel, his book-writing, advisory work with JASON, and his advocacy for the Superconducting Super Collider. Physicists, historians of science and interested readers will find the presentation engaging and often witty, as Weinberg reflects on his life in physics.

【簡介】 This volume is a comprehensive compilation of carefully selected questions at the PhD qualifying exam level, including many actual questions from Columbia University, University of Chicago, MIT, State University of New York at Buffalo, Princeton University, University of Wisconsin and the University of California at Berkeley over a twenty-year period. The topics covered in this book include basic nuclear properties, fission and fusion, symmetries in particle physics, grand unification theories, and experimental methods of high-energy particles, among many others.This latest edition has been updated with more problems and solutions while the original problems are modernized, excluding outdated questions and emphasizing those that rely on calculations. The problems range from fundamental to advanced in a wide range of topics, easily enhancing the student’s knowledge through workable exercises. Simple-to-solve problems play a useful role as a first check of the student’s level of knowledge whereas difficult problems will challenge the student’s capacity on finding solutions.

Modern Take on Physics, a - Volume 2: Classical and Quantum Field Theory (1版)

類似書籍推薦給您

【簡介】 These two volumes cover the classical topics typically taught in undergraduate physics courses and beyond. However, we teach classical physics using a very different language from traditional books, influenced by the language of modern physics, in a move to encourage a positive approach towards the latter subject. Based around the unifying concept of energy, we take a distinct approach to the organisation of material, presenting physics in a cohesive manner without separating topics such as mechanics, kinematics, thermodynamics, electricity, and magnetism. Instead, physics is revealed gradually, emphasising a holistic approach to science. Despite this peculiarity, we have maintained the conventional separation between Physics I and II to assist teachers in smoothly integrating these books into their courses.These innovative volumes present valuable new perspectives. Although their approach is bold, they will certainly prompt interesting reflections on traditional teachings. A significant portion of this second volume is committed to modern physics, including an introduction to the standard model of fundamental interactions. The old quantum mechanics is largely excluded in favour of quantum field theory, which we present in a manner accessible to undergraduate students.

Emergent Gauge Symmetries in Particle Physics and Cosmology (1版)

【簡介】 The Standard Model and General Relativity provide an excellent description of our present measurements in particle physics and gravitation. Yet we know that new physics is needed. Puzzles include tiny neutrino masses, baryogenesis (the matter-antimatter asymmetry in the Universe), dark energy and dark matter as well as the physics associated with primordial inflation.The book develops the idea of an emergent Standard Model: that its gauge symmetries and particles might be ＂born＂ in a topological like phase transition deep in the ultraviolet with the Standard Model parameters (the masses and couplings) linked to the stability of the vacuum. With emergence the gauge symmetries would ＂dissolve＂ in the extreme ultraviolet instead of extra unification. Neutrinos would be their own antiparticles. The cosmological constant scale comes out naturally in this approach, similar in size to the value of light Majorana neutrino masses. There are also interesting constraints on dark matter scenarios.Following an introduction to the Standard Model and the present status of our knowledge of fundamental interactions, the book discusses the key ideas of vacuum stability and emergent gauge symmetries. The phenomenology of an emergent Standard Model and its consequences for cosmology and early Universe physics are then explored. With a new generation of experiments both in particle and gravitational physics soon to begin plus expected advances in cosmology, the book serves both as an introduction and invitation to join new thinking in this physics with possible deep connections between the world of experiments and physics in the far ultraviolet.
