Ohmic vs Markovian heat bath — two-page
... In the high-T limit β → 0, the correlation tends to be time-local: βCXX (t) → 2ηδ(t). Thus the random force Xt becomes a classical white-noise: hXt Xu istoch = 2ηkB T δ(t − u). Now, replacing q̂ by q would yield the classical Langevin equation, its solution q(t) at V = 0 would be the Ornstein-Uhlenb ...

Arguably this is the interpretation which best fits the common understanding of time evolution as describing the changing state of a system whose identity through time is assumed. This is consistent with endurantism’s claim to provide an account of our intuitive grasp of persistence ...
