Light-induced coherence in an atom-cavity system
Christoph Georges, Jayson G. Cosme, Ludwig Mathey +1
We demonstrate light-induced formation of coherence in a cold atomic gas system that utilizes the suppression of a competing density wave (DW) order. The condensed atoms are placed…
Dynamical Control of Order in a Cavity-BEC System
Jayson G. Cosme, Christoph Georges, Andreas Hemmerich +1
We demonstrate dynamical control of the superradiant transition of cavity-BEC system via periodic driving of the pump laser. We show that the dominant density wave order of the sup…
Bosonic Topological Excitations from the Instability of a Quadratic Band Crossing
Guang-Quan Luo, Andreas Hemmerich, Zhi-Fang Xu
We investigate the interaction-driven instability of a quadratic band crossing arising for ultracold bosonic atoms loaded into a two-dimensional optical lattice. We consider the ca…
Rotation-symmetry-enforced coupling of spin and angular momentum for p-orbital bosons
Yongqiang Li, Jianmin Yuan, Andreas Hemmerich +1
Intrinsic spin angular-momentum coupling of an electron has a relativistic quantum origin with the coupling arising from charged-orbits, which does not carry over to charge-neutral…
