Speed limits of the trace distance for open quantum system
Satoshi Nakajima, Yasuhiro Utsumi
We investigate the speed limit of the state transformation in open quantum systems described by the Lindblad type quantum master equation. We obtain universal bounds of the total e…

Noether currents and generators of local gauge transformations in the covariant canonical formalism
Satoshi Nakajima
We investigate generators of local transformations in the covariant canonical formalism (CCF). The CCF treats space and time on an equal footing regarding the differential forms as…
