Correlations between rare events due to long-term memory
Apurba Biswas, Thomas Guérin
Rare events refer to qualitatively unlikely events whose realization can nevertheless have important consequences. Typically, the prediction of the kinetics of these events relies…

Mpemba effect in the relaxation of an active Brownian particle in a trap without metastable states
Apurba Biswas, R. Rajesh
We explore the role of activity in the occurrence of the Mpemba effect within a system of an active colloid diffusing in a potential landscape devoid of metastable minimum. The Mpe…

Mpemba effect on non-equilibrium active Markov chains
Apurba Biswas, Arnab Pal
We study the Mpemba effect on a non-equilibrium Markov chain that mimics the run and tumble motion of an active particle in a discrete energy landscape. The broken detailed balance…
