Critical behavior and crossover scaling in the Light-Heavy model
Shilpa Prakash, Mustansir Barma, Kabir Ramola
The Light-Heavy (LH) model involves two species of particles (light and heavy) coupled with a fluctuating surface (described by tilts). The dynamics include the inherent diffusion…

Stochastic systems with Bose-Hubbard interactions: Effects of bias on particles on a random comb
Swastik Majumder, Mustansir Barma
We study stochastic transport of interacting particles on a disordered network described by the random comb geometry. The model is defined on a one-dimensional backbone from which…
