Non-stationary Statistics and Energetics of Brownian Motion under Stochastic Harmonic Confinement
Deepak Gupta, Sabine H. L. Klapp
We investigate the positional statistics and thermodynamic properties of a Brownian particle confined in a Harmonic trap. The stiffness of the particle fluctuates in time as the sq…
Entropy production in non-reciprocal polar active mixtures
Kim L. Kreienkamp, Sabine H. L. Klapp
The out-of-equilibrium character of active systems is often twofold, arising from both the activity itself and from non-reciprocal couplings between constituents. A well-establishe…
Nonequilibrium fluctuations in a harmonic trap with annealed stochastic stiffness
Deepak Gupta, Sabine H. L. Klapp
We provide a comprehensive analysis of the positional dynamics and average thermodynamics of an overdamped Brownian particle subject to both, harmonic confinement and annealed diso…
Exponential Change of Relaxation Rate by Quenched Disorder
Jan Meibohm, Sabine H. L. Klapp
We determine the asymptotic relaxation rate of a Brownian particle in a harmonic potential perturbed by quenched Gaussian disorder, a simplified model for rugged energy landscapes…
Nonequilibrium dynamics and entropy production of a trapped colloidal particle in a complex nonreciprocal medium
Lea Fernandez, Siegfried Hess, Sabine H. L. Klapp
We discuss the two-dimensional motion of a Brownian particle that is confined to a harmonic trap and driven by a shear flow. The surrounding medium induces memory effects modelled…
Efficient control protocols for an active Ornstein-Uhlenbeck particle
Deepak Gupta, Sabine H. L. Klapp, David A. Sivak
Designing a protocol to efficiently drive a stochastic system is an active field of research. Here we extend such control theory to an active Ornstein-Uhlenbeck particle (AOUP) in…
