Abstract Quantum statistical mechanics governs metals, semiconductors, and neutron stars. Statistical mechanics spawned Planck’s invention of the quantum, and explains Bose condensation, superfluids, and superconductors. This chapter briefly describes these systems using mixed states, or more formally density matrices, and introducing ...

In general, the process that we use to prepare a system of atoms, molecules or whatever we want for a measurement produces many copies, but not all in the same quantum state. A pure state in which all the molecules, say, are in the same state, is a limiting case. In general, the system will be in a mixed state.

Before proceeding to the full quantum field-theoretic description of the macroscopic phenomena introduced in the previous chapter, we should first review the corresponding quantum-mechanical approach—quantum statistical mechanics.

Many-body theory stands at the foundation of modern quantum statistical mechanics. It is introduced here to graduate students in physics, chemistry, engineering and biology. The book provides a contemporary understanding of irreversibility, particularly in quantum systems.

The preceding formulation of statistical mechanics is perhaps the simplest application of probability theory to the many-body problem. Although it is consistent with the principles of quantum mechanics, it is not manifestly so. That is, the PME itself is based on the notions of information and measurement, but a general formulation should also ...
