Quantum particles in periodically driven harmonic trap — •Eoin Quinn and Masudul Haque — Max-Planck-Institut für Physik komplexer Systeme, Dresden, Germany

We describe the effect of periodically modulating the strength of a confining trap on a one-dimensional trapped quantum system. We consider the driven dynamics of strongly interacting bosons (Tonks Giradeau gas) and free fermions. Having a discrete spectrum, the system exhibits a set of resonances. Our description combines an exact solution with a Floquet analysis.
