Thermodynamics from relational imaginary time evolution
POSTER
Abstract
Thermodynamics is traditionally described with statistical ensembles in quantum or classical mechanics. Canonical typicality [1] has related thermodynamics for a system to ensembles of global energy eigenstates of system and its environment analyzing their cardinality. We derive thermodynamics from a single, maximally entangled global state extending the concept of relational time [2-4] to complex relational time.
