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…

Dynamics of Vibrated Grains
Abhishek Dhar, Supurna Sinha
We study number density distribution and the behavior of time correlation functions in the density of grains for a quasi-two dimensional system of vibrated grains. We study the sys…
