Power laws, anisotropy and center-of-mass conservation in mass transport processes
Aniket Samanta, Animesh Hazra, Punyabrata Pradhan
We present exact results for steady-state density correlation functions in conserved-mass transport processes with {\it anisotropic}, reflection-symmetric hopping on a dimensio…
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…
Hyperuniformity in mass transport processes with center-of-mass conservation: Some exact results
Animesh Hazra, Anirban Mukherjee, Punyabrata Pradhan
We characterize steady-state static and dynamic properties in a broad class of mass transport processes on a periodic hypercubic lattice of volume , where both mass and {\it c…
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…
