Cover time statistics of one-dimensional Brownian motion under stochastic resetting
Anirban Ghosh, Sanjib Sabhapandit
We investigate the effect of stochastic resetting on the statistics of the cover time of a one-dimensional Brownian motion with a diffusion constant , confined to a finite inter…
Sluggish quantum mechanics of noninteracting fermions with spatially varying effective mass
Giuseppe Del Vecchio Del Vecchio, Manas Kulkarni, Satya N. Majumdar +1
We analyze a class of one-dimensional quantum systems characterized by a position-dependent kinetic term arising as the continuum limit of an inhomogeneous tight-binding model with…
Proxitaxis: an adaptive search strategy based on proximity and stochastic resetting
Giuseppe Del Vecchio Del Vecchio, Manas Kulkarni, Satya N. Majumdar +1
We introduce \emph{proxitaxis}, a simple search strategy where the searcher has only information about the distance from the target but not the direction. The strategy consists of…
Dynamically emergent correlations in a Brownian gas with diffusing diffusivity
Nikhil Mesquita, Satya N. Majumdar, Sanjib Sabhapandit
We study a gas of Brownian particles in the presence of a common stochastic diffusivity , where represents a one-dimensional Brownian motion at time . St…
Hysteresis in magnets
Deepak Dhar, Sanjib Sabhapandit
We provide an overview of studies of hysteresis in models of magnets. We discuss the shape of the hysteresis loop, dynamical symmetry breaking, and the dependence of the area of th…
Hydrodynamics of a hard-core active lattice gas
Ritwik Mukherjee, Soumyabrata Saha, Tridib Sadhu +2
We present a fluctuating hydrodynamic description of an active lattice gas model with excluded volume interactions that exhibits motility-induced phase separation under appropriate…
