Fast-forward scheme reexamined: Choice of time and quantization

Quantum Physics 2022-01-04 v3 Statistical Mechanics

Abstract

The fast-forward scheme for accelerating time evolution of quantum states through change of time is reexamined. Dirac's homogeneous formalism for classical dynamics and canonical quantization warrant that the Schr\"odinger equation is covariant under reparametrization of time. From this, it is concluded that the scheme does not attain its objective.
