Impact of chirality on active Brownian particle: Exact moments in two and three dimensions
Anweshika Pattanayak, Amir Shee, Debasish Chaudhuri +1
In this work, we investigate the effects of chirality, accounting for translational diffusion, on active Brownian particles in two and three dimensions. Despite the inherent comple…
Dynamical crossovers and correlations in a harmonic chain of active particles
Subhajit Paul, Abhishek Dhar, Debasish Chaudhuri
We explore the dynamics of a tracer in an active particle harmonic chain, investigating the influence of interactions. Our analysis involves calculating mean-squared displacements…
Exact moments and re-entrant transitions in the inertial dynamics of active Brownian particles
Manish Patel, Debasish Chaudhuri
In this study, we investigate the behavior of free inertial Active Brownian Particles (ABP) in the presence of thermal noise. While finding a closed-form solution for the joint dis…
When does an active bath behave as an equilibrium one?
Shubhendu Shekhar Khali, Fernando Peruani, Debasish Chaudhuri
Active baths are characterized by a non-Gaussian velocity distribution and a quadratic dependence with active velocity of the kinetic temperature and diffusion coefficient. W…
Finite temperature dynamical quantum phase transition in a non-Hermitian system
Debashish Mondal, Tanay Nag
We investigate the interplay between the non-Hermiticity and finite temperature in the context of mixed state dynamical quantum phase transition (MSDQPT). We consider a -wave su…
Anomaly in dynamical quantum phase transition in non-Hermitian system with extended gapless phases
Debashish Mondal, Tanay Nag
The dynamical quantum phase transitions (DQPTs) and the associated winding numbers have been extensively studied in the context Hermitian system. We consider the non-Hermitian anal…
