Satya N. Majumdar 1, Dibyendu Das 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 71 (2005) 036129 We study the persistence properties in a simple model of two coupled interfaces characterized by heights h_1 and h_2 respectively, each growing over a d-dimensional substrate. The first interface evolves independently of the second and can correspond to any generic […]

Apoorva Nagar 1, Mustansir Barma 1, Satya N. Majumdar 2 Physical Review Letters 94 (2005) 240601 We study the clustering properties of particles sliding downwards on a fluctuating surface evolving through the Kardar-Parisi-Zhang equation, a problem equivalent to passive scalars driven by a Burgers fluid. Monte Carlo simulations on a discrete version of the problem in one dimension reveal that particles

Beyond the particle-hole symmetric case for which a simple proof exists, this has been known only empirically. Here we prove the

Michael J. Kearney 1, Satya N. Majumdar 2 Journal of Physics A 38 (2005) 4097 The area swept out under a one-dimensional Brownian motion till its first-passage time is analysed using a backward Fokker-Planck technique. We obtain an exact expression of the area distribution for the zero drift case, and provide various asymptotic results for the non-zero drift case,

The long-range and anisotropic magnetic dipole-dipole interaction leads to an anisotropic deformation of the expanding Cr-BEC which depends on the orientation of the atomic dipole moments.

Tobias Paul 1, Patricio Leboeuf 2, Nicolas Pavloff 2, Klaus Richter 1, Peter Schlagheck 1 Physical Review A: Atomic, Molecular and Optical Physics 72 (2005) 063621 We study the coherent flow of a guided Bose-Einstein condensate incident over a disordered region of length L. We introduce a model of disordered potential that originates from magnetic fluctuations inherent to microfabricated guides. This model allows for analytical
