Abstract

The impact of high intensity optical lattices on atomic and molecular gases in continuum flow regime is studied. A two-step kinetic/continuum approach is applied. The kinetic step uses the DSMC method to model the gas-lattice Interaction over the pulse period. The continuum step based on the solution of Navier-Stokes equations utilizes the kinetic solution as initial condition, and predicts the gas evolution at spatial and temporal scales larger than those associated with the optical lattice. The numerical approach is applied to analyze the propagation of an acoustic signal created by the lattice, the energy deposition from lattice to gas, and gas mixing.
