Network analysis for steady-state current fluctuations under finite affinity: Application to Brownian computation
Yasuhiro Utsumi
A graph-theoretic analysis of the steady-state current noise in master equations under a finite thermodynamic force (affinity) is presented. The incidence matrix twisted by a finit…
Interatomic spin-orbit interaction in a -orbital helical atomic chain
Takemitsu Kato, Yasuhiro Utsumi, Ora Entin-Wohlman +1
We derive the interatomic spin-orbit interaction (SOI) from a helical atomic chain composed of -orbitals with intra-atomic SOI, which exhibits a helical state--a potential origi…
Join gate with memory in token-conserving Brownian circuits and the thermodynamic cost
Yasuhiro Utsumi
The token-based Brownian circuit harnesses the Brownian motion of particles for computation. The conservative join (CJoin) is a circuit element that synchronizes two Brownian parti…
Network analysis for the steady-state thermodynamic uncertainty relation
Yasuhiro Utsumi
We perform network analysis of a system described by the master equation to estimate the lower bound of the steady-state current noise, starting from the level 2.5 large deviation…
AC transport and full-counting statistics of molecular junctions in the weak electron-vibration coupling regime
A. Ueda, Y. Utsumi, Y. Tokura +2
The coupling of the charge carriers passing through a molecule bridging two bulky conductors with local vibrational modes of the molecule, gives rise to distinct features in the el…
Fluctuation theorem for heat transport probed by a thermal electrode
Y. Utsumi, O. Entin-Wohlman, A. Aharony +2
We analyze the full-counting statistics of the electric heat current flowing in a two-terminal quantum conductor whose temperature is probed by a third electrode ("probe electrode"…
