Simulating sympathetic cooling of atomic mixtures in nonlinear traps

Francisco Jauffred, Roberto Onofrio, Bala Sundaram

We discuss the dynamics of sympathetic cooling of atomic mixtures in realistic, nonlinear trapping potentials using a microscopic effective model developed earlier for harmonic tra…

Ehrenfest Dynamics and Frictionless Cooling Methods

S. Choi, R. Onofrio, B. Sundaram

Recently introduced methods which result in shortcuts to adiabaticity, particularly in the context of frictionless cooling, are rederived and discussed in the framework of an appro…

Squeezing and robustness of frictionless cooling strategies

S. Choi, R. Onofrio, B. Sundaram

Quantum control strategies that provide shortcuts to adiabaticity are increasingly considered in various contexts including atomic cooling. Recent studies have emphasized practical…

Optimized sympathetic cooling of atomic mixtures via fast adiabatic strategies

Stephen Choi, Roberto Onofrio, Bala Sundaram

We discuss fast frictionless cooling techniques in the framework of sympathetic cooling of cold atomic mixtures. It is argued that optimal cooling of an atomic species - in which t…

Semiclassical dynamics of atomic Bose-Einstein condensates

S. Choi, B. Sundaram

An atomic Bose-Einstein condensate (BEC) is often described as a macroscopic object which can be approximated by a coherent state. This, on the surface, would appear to indicate th…
