Wave packet dynamics in parabolic optical lattices: From Bloch oscillations to long-range dynamical tunneling
Usman Ali, Martin Holthaus, Torsten Meier
We investigate the dynamics of wave packets in a parabolic optical lattice formed by combining an optical lattice with a global parabolic trap. Our study examines the phase space r…

Floquet dynamics of ultracold atoms in optical lattices with a parametrically modulated trapping potential
Usman Ali, Martin Holthaus, Torsten Meier
Experiments with ultracold atoms in optical lattices usually involve a weak parabolic trapping potential which merely serves to confine the atoms, but otherwise remains negligible.…
