Autonomous Brownian gyrators: A study on gyrating characteristics

We study the nonequilibrium steady-state (NESS) dynamics of two-dimensional Brownian gyrators under harmonic and nonharmonic potentials via computer simulations analyses based on Fokker-Planck equation, while our cases feature a double-well potential an isotropic quartic potential. In particular, we report two simple methods that can help understand gyrating patterns. For potentials, use equation to survey NESS dynamical characteristics; i.e., currents gyrate along equiprobability contours stationary point flow coincides with minimum. As contrast, results in show these properties are largely absent, as patterns very distinct from those corresponding probability distributions. Furthermore, observe critical case potential, where contribution pattern becomes do not circulate about near minima even at low temperatures.
