New Formulation of Statistical Mechanics using Thermal Pure Quantum States
Sho Sugiura, Akira Shimizu
We formulate statistical mechanics based on a pure quantum state, which we call a ``thermal pure quantum (TPQ) state''. A single TPQ state gives not only equilibrium values of mech…

Canonical Thermal Pure Quantum State
Sho Sugiura, Akira Shimizu
A thermal equilibrium state of a quantum many-body system can be represented by a typical pure state, which we call a thermal pure quantum (TPQ) state. We construct the canonical T…
