Odd diffusion and power-law correlations in chiral mass-transport processes
Koushik Das, Animesh Hazra, Punyabrata Pradhan
We study mass-conserving Markov jump processes on a square lattice, where masses hop with a preferred rotational sense, thus breaking both time-reversal and mirror symmetries. We c…

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…
