Description

The density matrix of a subsystem of a chaotic many-body system in an energy eigenstate can be modeled by a hermitian matrix that has been randomly selected from a suitable fixed-trace distribution; at leading order in system volume, the result is a thermal density matrix. I will discuss subleading corrections that arise at finite temperature, but which are usually absent at infinite temperature.
