Nonequilibrium steady states of the isotropic classical magnet
Jayajit Das, Madan Rao, Sriram Ramaswamy
We drive a d-dimensional Heisenberg magnet using a spatially anisotropic current of mobile particles or heat. The continuum Langevin equation is analyzed using a dynamical renormal…
Arrested States of Solids
Madan Rao, Surajit Sengupta
Solids produced as a result of a fast quench across a freezing or a structural transition get stuck in long-lived metastable configurations of distinct morphology, sensitively depe…
Conserved Ordering Dynamics of Heisenberg Spins with Torque
Jayajit Das, Madan Rao
We show that a torque induced by the local molecular field drives the zero-temperature ordering dynamics of a conserved Heisenberg magnet to a new fixed point, characterised by exp…
First Passage Times and Time-Temperature-Transformation curves for Martensites
Madan Rao, Surajit Sengupta
Martensites are long-lived nonequilibrium structures produced following a quench across a solid state structural transition. In a recent paper (Phys. Rev. Lett. 78, 2168 (1997)), w…
Droplet Free Energy Functional for the Morphology of Martensites
Madan Rao, Surajit Sengupta
Martensites are metastable phases, possessing a characteristic morphology, usually formed during a fast quench accross a structural transition. We attempt to understand these morph…
Kinetics of Phase Ordering in a Two-Component Fluid Membrane
P. B. Sunil Kumar, Madan Rao
We present a novel Monte Carlo simulation of the phase separation dynamics of a model fluid membrane. Such a phase segregation induces shape changes of the membrane and results in…
