Many-Particle Quantum Systems |
In General > s.a. quantum statistical
mechanics; semiclassical quantum mechanics.
* Principle of local distinguishability:
An arbitrary physical state of a bipartite system can be determined by the combined
statistics of local measurements performed on the subsystems.
* History: Founded by papers by Dirac
and Heisenberg on identical particles.
* Examples: Atomic or molecular clusters,
atoms or molecules, nuclei, nucleons; Systems with strong pair correlations can be
modeled by the exactly solvable Richardson-Gaudin models.

Approaches, Techniques > s.a. Bethe Ansatz.
* Approaches: The first
approximation is the mean-field theory, which is exact only for free
systems; The next approximation uses 2-body correlations, random phase
approximation, and the Bethe Ansatz; The main approach is the coupled
cluster method; Density-functional theory; A simple technique to obtain
approximate but reliable ground state energies is envelope theory.
* Information scrambling: The
delocalization of information under many-body dynamics; Out-of-time-order
correlators have been proposed to probe it.
