Enhancement in Breaking of Time-reversal Invariance in the Quantum Kicked Rotor
Ramgopal Agrawal, Akhilesh Pandey, Sanjay Puri
We study the breaking of time-reversal invariance (TRI) by the application of a magnetic field in the quantum kicked rotor (QKR), using Izrailev's finite-dimensional model. There i…
Asymptotic States of Ising Ferromagnets with Long-range Interactions
Ramgopal Agrawal, Federico Corberi, Ferdinando Insalata +1
It is known that, after a quench to zero temperature (), two-dimensional () Ising ferromagnets with short-range interactions do not always relax to the ordered state. The…
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…
