Thermal pure state path integral and emergent symmetry
Shin-ichi Sasa, Sho Sugiura, Yuki Yokokura
We investigate a thermally isolated quantum many-body system with an external control represented by a time-dependent parameter. We formulate a path integral in terms of thermal pu…
Nonequilibrium fluctuation response relation in a time scale separated system
Shou-Wen Wang, Kyogo Kawaguchi, Shin-ichi Sasa +1
We present a theoretical framework to analyze the violation of fluctuation-response relation (FRR) for any observable from a finite Markov system with two well-separated time scale…
Gaussian white noise as a resource for microscopic engines
Andreas Dechant, Adrian Baule, Shin-ichi Sasa
We show that uncorrelated Gaussian noise, despite its paradigmatic association with thermal equilibrium, can drive a system out of equilibrium and can serve as a resource from whic…
Replica symmetry breaking in trajectory space for the trap model
Masahiko Ueda, Shin-ichi Sasa
We study the localization in the one-dimensional trap model in terms of statistical mechanics of trajectories. By numerically investigating overlap between trajectories of two part…
Universal Form of Stochastic Evolution for Slow Variables in Equilibrium Systems
Masato Itami, Shin-ichi Sasa
Nonlinear, multiplicative Langevin equations for a complete set of slow variables in equilibrium systems are generally derived on the basis of the separation of time scales. The fo…
Entropy production of nano systems with timescale separation
Shou-Wen Wang, Kyogo Kawaguchi, Shin-ichi Sasa +1
Energy flow in bio-molecular motors and machines are vital to their function. Yet experimental observations are often limited to a small subset of variables that participate in ene…
