Quantum statistical mechanics is statistical mechanics applied to quantum mechanical systems. It relies on constructing density matrices that describe quantum systems in thermal equilibrium.

Quantum statistical mechanics governs most of solid-state physics (met-als, semiconductors, and glasses) and parts of molecular physics and astrophysics (white dwarfs, neutron stars).

The statistical inter-pretation of quantum mechanics made its way progressively since the early days of the theory. We summarize the main historical steps and then we outline how the randomness gains …

The book provides a contemporary understanding of irreversibility, particularly in quantum systems. It explains entropy production in quantum kinetic theory and in the master equation formulation of non …

Nov 14, 2025 · Quantum statistical mechanics is a research area that extends classical statistical mechanics to systems governed by quantum theory, providing a rigorous framework for describing …

Quantum Statistical Mechanics is a branch of physics that connects the macroscopic properties of matter with its microscopic characteristics, primarily focusing on the behavior of atoms and molecules.

In quantum mechanics, identical particles of half-integer spin, like the electron, can never occupy the same state, by the Pauli exclusion principle. These particles obey Fermi-Dirac statistics.

Overall, quantum statistical mechanics is a fundamental area of study that provides a deep understanding of the statistical behaviors of quantum systems, bridging the gap between microscopic …
