Domain Growth and Aging in the Random Field XY Model: A Monte Carlo Study
Ramgopal Agrawal, Manoj Kumar, Sanjay Puri
We use large-scale Monte Carlo simulations to obtain comprehensive results for domain growth and aging in the random field XY model in dimensions . After a deep quench from…
Coexistence of coarsening and mean field relaxation in the long-range Ising chain
Federico Corberi, Alessandro Iannone, Manoj Kumar +2
We study the kinetics after a low temperature quench of the one-dimensional Ising model with long range interactions between spins at distance decaying as . For ,…
Growth Kinetics and Aging Phenomena in a Frustrated System
Manoj Kumar, Federico Corberi, Eugenio Lippiello +1
We study numerically the ordering kinetics in a two-dimensional Ising model with random coupling where the fraction of antiferromagnetic links can be gradually tuned. We show t…
Transport, correlations, and chaos in a classical disordered anharmonic chain
Manoj Kumar, Anupam Kundu, Manas Kulkarni +2
We explore transport properties in a disordered nonlinear chain of classical harmonic oscillators and thereby identify a regime exhibiting behavior analogous to that seen in quantu…
Effects of Frustration on Fluctuation-dissipation Relations
Federico Corberi, Manoj Kumar, Eugenio Lippiello +1
We study numerically the aging properties of the two-dimensional Ising model with quenched disorder considered in our recent paper [Phys. Rev. E 95, 062136 (2017)], where frustrati…
Equilibrium structure and off-equilibrium kinetics of a magnet with tunable frustration
Federico Corberi, Manoj Kumar, Eugenio Lippiello +1
We study numerically a two-dimensional random-bond Ising model where frustration can be tuned by varying the fraction of antiferromagnetic coupling constants. At low temperatur…
