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…

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…
Excess entropy production in quantum system: Quantum master equation approach
Satoshi Nakajima, Yasuhiro Tokura
For open systems described by the quantum master equation (QME), we investigate the excess entropy production under quasistatic operations between nonequilibrium steady states. The…
Reconsideration of De Donder-Weyl theory by covariant analytic mechanics
Satoshi Nakajima
We show that the covariant analytic mechanics (CAM) is closely related to the De Donder-Weyl (DW) theory. To treat space and time on an equal footing, the DW theory introduces …
Application of covariant analytic mechanics with differential forms to gravity with Dirac field
Satoshi Nakajima
We apply the covariant analytic mechanics with the differential forms to the Dirac field and the gravity with the Dirac field. The covariant analytic mechanics treats space and tim…
Quantum adiabatic pumping by modulating tunnel phase in quantum dots
Masahiko Taguchi, Satoshi Nakajima, Toshihiro Kubo +1
In a mesoscopic system, under zero bias voltage, a finite charge is transferred by quantum adiabatic pumping by adiabatically and periodically changing two or more control paramete…

Satoshi Nakajima, Masahiko Taguchi, Toshihiro Kubo +1
We investigate the pumped charge and spin at zero-bias by adiabatic modulation of two control parameters using the full counting statistics with quantum master equation approach. F…
