Population dynamics in Floquet realisation of Harper-Hofstadter Hamiltonian
(2015-04-21)
We study the recent Floquet-realisation of the Harper-Hofstadter model in a gas of cold bosonic atoms. We study in detail the scattering processes in this system in the weakly interacting regime due to the interplay of ...
Synthetic dimensions in the strong-coupling limit: supersolids and pair-superfluids
(2016-06-29)
We study the many-body phases of bosonic atoms with N internal states confined to a 1D optical lattice under the influence of a synthetic magnetic field and strong repulsive interactions. The N internal states of the atoms ...
Scattering theory for Floquet-Bloch states
(2014-10-20)
Motivated by recent experimental implementations of artificial gauge fields for gases of cold atoms, we study the scattering properties of particles that are subjected to time-periodic Hamiltonians. Making use of Floquet ...
