Memory-induced active particle ratchets: Mean currents and large deviations
Venkata D. Pamulaparthy, Rosemary J. Harris
We analyse a continuous-time random walk model with stochastic reversals of direction. There is no external potential but the reorientation mechanism generates a non-zero current f…
First-Passage-Time Asymmetry for Biased Run-and-Tumble Processes
Yonathan Sarmiento, Benjamin Walter, Debraj Das +3
We explore first-passage phenomenology for biased active processes with a renewal-type structure, focusing in particular on paradigmatic run-and-tumble models in both discrete and…
Towards neural reinforcement learning for large deviations in nonequilibrium systems with memory
Venkata D. Pamulaparthy, Rosemary J. Harris
We introduce a reinforcement learning method for a class of non-Markov systems; our approach extends the actor-critic framework given by Rose et al. [New J. Phys. 23 013013 (2021)]…
