Work distribution functions for hysteresis loops in a single-spin system
Rahul Marathe, Abhishek Dhar
We compute the distribution of the work done in driving a single Ising spin with a time-dependent magnetic field. Using Glauber dynamics we perform Monte-Carlo simulations to find…
Brownian motion and magnetism
Supurna Sinha, Joseph Samuel
We present an interesting connection between Brownian motion and magnetism. We use this to determine the distribution of areas enclosed by the path of a particle diffusing on a sph…
Levy statistical fluctuations from a Random Amplifying Medium
Divya Sharma, Hema Ramachandran, N. Kumar
We report the studies of emission from a novel random amplifying medium that we term a ``Levy Laser'' due to the non-Gaussian statistical nature of its emission over the ensemble o…
Fluctuation induced chiral symmetry breaking in autocatalytic reaction-diffusion systems
V. S. Gayathri, Madan Rao
We show how spatiotemporal fluctuations can induce spontaneous symmetry breaking in systems which are perfectly symmetric in the absence of fluctuations. We illustrate this in the…
