Spintronic reservoir computing without driving current or magnetic field
Tomohiro Taniguchi, Amon Ogihara, Yasuhiro Utsumi +1
Recent studies have shown that nonlinear magnetization dynamics excited in nanostructured ferromagnets are applicable to brain-inspired computing such as physical reservoir computi…
Electronic and Spin States at Edges of Finite -orbital Helical Atomic Chain
Takemitsu Kato, Yasuhiro Utsumi, Ora Entin-Wohlman +1
In connection to the chiral-induced spin-selectivity (CISS) effect, we theoretically analyze the electronic and spin states of edges of a finite -orbital helical atomic chain wi…
Thermodynamic cost of Brownian computers in the stochastic thermodynamics of resetting
Yasuhiro Utsumi, Dimitry Golubev, Ferdinand Peper
We analyze the thermodynamic cost of a logically reversible Brownian Turing machine operating in the first-passage time protocol based on the stochastic thermodynamics of resetting…
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…
Spin-filtering in a -orbital helical atomic chain
Yasuhiro Utsumi, Takemitsu Kato, Ora Entin-Wohlman +1
We theoretically analyze spin filtering in two-terminal systems, induced by the spin-orbit interaction (SOI), as a possible origin of the ``chirality-induced spin selectivity'' (CI…
Generalized speed limits for classical stochastic systems and their applications to relaxation, annealing, and pumping processes
Kazutaka Takahashi, Yasuhiro Utsumi
We extend the speed limit of a distance between two states evolving by different generators for quantum systems [K. Suzuki and K. Takahashi, Phys. Rev. Res. 2, 032016(R) (2020)] to…
