Quantum particle in a parabolic lattice in the presence of a gauge field
Andrey R. Kolovsky, Fabian Grusdt, Michael Fleischhauer
We analyze the eigenstates of a two-dimensional lattice with additional harmonic confinement in the presence of an artificial magnetic field. While the softness of the confinement…

Topological edge states in the one-dimensional super-lattice Bose-Hubbard model
Fabian Grusdt, Michael Höning, Michael Fleischhauer
We analyze interacting ultra-cold bosonic atoms in a one-dimensional (1D) super-lattice potential with alternating tunneling rates t_1 and t_2 and inversion symmetry, which is the…
