Stochastic Energetics of Non-uniform Temperature Systems
Miki Matsuo, Shin-ichi Sasa
We propose an energetic interpretation ofstochastic processes described by Langevin equations with non-uniform temperature. In order to avoid Itô-Stratonovich dilemma, we start wit…
Dynamical Scaling Behavior of the Swift-Hohenberg Equation Following a Quench to the Modulated State
Qing Hou, Shin-ichi Sasa, Nigel Goldenfeld
We study the kinetics of phase transitions in a Rayleigh-Benard system after onset of convection using 2D Swift-Hohenberg equation. An initially uniform state evolves to one whose…
Thermodynamic entropy and excess information loss in dynamical systems with time-dependent Hamiltonian
S. Sasa, T. S. Komatsu
We study a dynamical system with time dependent Hamiltonian by numerical experiments so as to find a relation between thermodynamics and chaotic nature of the system. Excess inform…
Numerical simulations on Szilard's engine and information erasure
Takahiro Hatano, Shin-ichi Sasa
We present a computational model for Szilard's engine and the information discarding process. Taking advantage of a fact that the one is essentially the reversed cycle of the other…
