Resonant Pair Exchange and Percolation in the Disordered Hubbard Model
Dariush Heidarian, Mustansir Barma, Nandini Trivedi
We show that the effect of disorder on a Mott-Hubbard insulator of interacting electrons produces a quantum phase transition from an antiferromagnetic to a paramagnetic phase gover…
Orientational correlations and the effect of spatial gradients in the equilibrium steady state of hard rods in 2D : A study using deposition-evaporation kinetics
Mahendra D. Khandkar, Mustansir Barma
Deposition and evaporation of infinitely thin hard rods (needles) is studied in two dimensions using Monte Carlo simulations. The ratio of deposition to evaporation rates controls…
Clustering of advected passive sliders on a fluctuating surface
Apoorva Nagar, Mustansir Barma, Satya N. Majumdar
We study the clustering properties of advected, non-interacting,passive scalar particles in a Burgers fluid with noise, a problem which maps to that of passive sliding particles mo…
Phase separation driven by a fluctuating two-dimensional self-affine potential field
G. Manoj, Mustansir Barma
We study phase separation in a system of hard-core particles driven by a fluctuating two-dimensional self-affine potential landscape which evolves through Kardar-Parisi-Zhang (KPZ)…
Phase Diagram of a Two-Species Lattice Model with a Linear Instability
Sriram Ramaswamy, Mustansir Barma, Dibyendu Das +1
We review recent progress in understanding the full phase diagram of a one-dimensional, driven, two-species lattice model [Lahiri and Ramaswamy, PRL 79 (1997) 1150] in which the mo…
Fluctuation-Dominated Phase Ordering Driven by Stochastically Evolving Surfaces
Dibyendu Das, Mustansir Barma, Satya N. Majumdar
We study a new kind of phase ordering phenomenon in coarse-grained depth (CD) models of the hill-valley profile of fluctuating surfaces with zero overall tilt, and for hard-core pa…
