Variational superposed Gaussian approximation for time-dependent solutions of Langevin equations
Yoshihiko Hasegawa
We propose a variational superposed Gaussian approximation (VSGA) for dynamical solutions of Langevin equations subject to applied signals, determining time-dependent parameters of…

Bistable stochastic processes in the q-exponential family
Yoshihiko Hasegawa, Masanori Arita
Stochastic bistable systems whose stationary distributions belong to the q-exponential family are investigated using two approaches: (i) the Langevin model subjected to additive an…

Noise-intensity fluctuation in Langevin model and its higher-order Fokker-Planck equation
Yoshihiko Hasegawa, Masanori Arita
In this paper, we investigate a Langevin model subjected to stochastic intensity noise (SIN), which incorporates temporal fluctuations in noise-intensity. We derive a higher-order…
