SLD Fisher information for kinetic uncertainty relations

Satoshi Nakajima, Yasuhiro Utsumi

We investigate a symmetric logarithmic derivative (SLD) Fisher information for kinetic uncertainty relations (KURs) of open quantum systems described by the GKSL quantum master equ…

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…

Asymptotic expansion of the solution of the master equation and its application to the speed limit

Satoshi Nakajima, Yasuhiro Utsumi

We investigate an asymptotic expansion of the solution of the master equation under the modulation of control parameters. In this case, the non-decaying part of the solution become…

Generators of local gauge transformations in the covariant canonical formalism of fields

Satoshi Nakajima

We investigate generators of local gauge transformations in the covariant canonical formalism (CCF) for matter fields, gauge fields and the second order formalism of gravity. The C…

Theoretical studies on quantum pump and excess entropy production: Quantum master equation approach

Satoshi Nakajima

In this thesis, we considered quantum systems coupled to several baths. We supposed that the system state is governed by the quantum master equation (QME). We investigated the quan…
