Splash in an inhomogeneous gas in one dimension: Exact analysis and molecular dynamics simulations
Amit Kumar, R. Rajesh
We investigate the splash phenomenon resulting from the energy input at the interface between a vacuum and an inhomogeneous gas with density profile . The ene…

Shock propagation in a driven hard sphere gas: molecular dynamics simulations and hydrodynamics
Amit Kumar, R. Rajesh
The continuous injection of energy in a stationary gas creates a shock wave that propagates radially outwards. We study the hydrodynamics of this disturbance using event driven mol…

Exact calculation of the large deviation function for -nary coalescence
R. Rajesh, V. Subashri, Oleg Zaboronski
We study probabilities of rare events in the general coalescence process, , where . For arbitrary , by rewriting these probabilities in terms…
