& Sondheimer, Greens Functions for Solid State Physicists Fetter, A. The wave functions of individual particles can be added together to create a wave function for a system, so quantum theory allows physicists to examine many particles at once. Statistical mechanics in quantum theory: counting states. All objects can and do exist in superpositions of multiple states at the same time, but for a massive object containing many particles bound together, those superpositions fall apart very quickly. References: Griffiths In statistical mechanics the central assumption is that all states with a given energy are equally probable, if the system is in thermal equilibrium, which means that it is not exchanging energy with its surroundings.

Quantum field theory of point particles and strings. The 2013 Boulder school will concentrate on two aspects of many-body quantum physics: disorder and dynamics. Fetter, John Dirk Walecka, Quantum. Quantum field theory of non-equilibrium states. This is quite a hefty In classical physics, the allowed energy levels for a collection of particles form a continuous set, so there are infinitely many possible states. Indeed the When the mass is very small classical physics breaks down, but this does not mean quantum physics breaks down at large scales and indeed, despite many experiments to isolate a mesoscopic region where quantum physics breaks down, no such region has been found. Quantum field theory of many-body systems. In principle, using a quantum approach to predicting the behavior of a macroscopic (large mass) localized particle would be expected to yield the same answer as a classical approach. & Walecka, Quantum Theory of Many-Particle Systems Hedin, L.
