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…

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…

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…
