From quantum to classical without ħ → 0

Publication date: Available online 20 June 2018Source: Physics Letters AAuthor(s): E. GozziAbstractIn this paper we put forward some simple rules which can be used in order to pass from the quantum Moyal evolution operator to the classical one of Liouville without taking the limit of ħ→0. These rules involve the averaging over some auxiliary variables.
