Ideal Gases in Time-Dependent Traps



G M. Bruun, Charles W. Clark


We investigate theoretically the properties of an ideal trapped gas in a time-dependent harmonic potential. Using a scaling formalism, we are able to present exact analytical results for two important classes of experiments: free expansion of the gas upon release of the trap; and the response of the gas to a harmonic modulation of the trapping potential. We present specific results relevant to current experiments on trapped Fermions.
