Fast-forward scheme reexamined: Choice of time and quantization
arXiv:2007.06384 · doi:10.1016/j.rinp.2021.105051
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 Schrödinger equation is covariant under reparametrization of time. From this, it is concluded that the scheme does not attain its objective.
