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…

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…

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…
