Anomalous current fluctuations and mobility-driven clustering

Tanmoy Chakraborty, Punyabrata Pradhan

We study steady-state current fluctuations in hardcore lattice gases on a ring of sites, where particles perform symmetric, {\it extended-ranged} hopping. The hop length is…

Generic power laws in higher-dimensional lattice models with multidirectional hopping

Animesh Hazra, Tanmoy Chakraborty, Anirban Mukherjee +1

We show that, on a dimensional hypercubic lattice with , conserved-mass transport processes, with {\it multidirectional} hopping that respect all symmetries of the lattice…

Current fluctuations in the symmetric zero-range process below and at critical density

Tanmoy Chakraborty, Punyabrata Pradhan, Kavita Jain

Characterizing current fluctuations in a steady state is of fundamental interest and has attracted considerable attention in the recent past. However, the bulk of the studies are l…

Time-dependent properties of run-and-tumble particles. II.: Current fluctuations

Tanmoy Chakraborty, Punyabrata Pradhan

We investigate steady-state current fluctuations in two models of run-and-tumble particles (RTPs) on a ring of sites, for \textit{arbitrary} tumbling rate and dens…

Time-dependent properties of run-and-tumble particles: Density relaxation

Tanmoy Chakraborty, Punyabrata Pradhan

We characterize collective diffusion of hardcore run-and-tumble particles (RTPs) by explicitly calculating the bulk-diffusion coefficient in two minimal models on a d…

Transport and fluctuations in mass aggregation processes: mobility driven clustering

Subhadip Chakraborti, Tanmoy Chakraborty, Arghya Das +2

We calculate the bulk-diffusion coefficient and the conductivity in a broad class of conserved-mass aggregation processes on a ring of discrete sites. These processes involve chipp…
