51Perturbation theory (quantum mechanics) — In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a …
52Partition function (quantum field theory) — In quantum field theory, we have a generating functional, Z [J] of correlation functions and this value, called the partition function is usually expressed by something like the following functional integral::Z [J] = int mathcal{D}phi e^{i(S… …
53Continuous quantum computation — Two major motivations for studying continuous quantum computation are: Many scientific problems have continuous mathematical formulations. Examples of such formulations are Path integration Feynman Kac path integration Schrödinger equation In… …
54The Center for Complex Quantum Systems — [The research institute was formerly named The Ilya Prigogine Center for Studies in Statistical Mechanics and Complex Systems.] is a research institute within the Department of Physics of The University of Texas at Austin in the United States.The …
55Philosophy of thermal and statistical physics — The philosophy of thermal and statistical physics is one of the major subdisciplines of the philosophy of physics. Its subject matter is classical thermodynamics, statistical mechanics, and related theories. Its central questions include: What is …
56History of loop quantum gravity — General relativity is the theory of gravitation published by Albert Einstein in 1915. According to it, the force of gravity is a manifestation of the local geometry of spacetime. Mathematically, the theory is modelled after Bernhard Riemann s… …
57Monte Carlo method in statistical physics — Monte Carlo in statistical physics refers to the application of the Monte Carlo method to problems in statistical physics, or statistical mechanics. Contents 1 Overview 2 Importance sampling 2.1 Canonical …
58Heisenberg model (quantum) — The Heisenberg model is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spin of the magnetic systems are treated quantum mechanically. In the prototypical Ising model,… …
59Matrix mechanics — Quantum mechanics Uncertainty principle …
60Interpretation of quantum mechanics — An interpretation of quantum mechanics is a statement which attempts to explain how quantum mechanics informs our understanding of nature. Although quantum mechanics has received thorough experimental testing, many of these experiments are open… …
