Ultra-cold atoms quantum tunneling through single and double optical barriers
Roy Eid, Alfred Hammond, Lucas Lavoine +1
We realize textbook experiments on Bose-Einstein condensate tunnelling through thin repulsive potential barriers. In particular, we demonstrate atom tunnelling though a single opti…

Decoupled sound and amplitude modes in trapped dipolar supersolids
Jens Hertkorn, Philipp Stürmer, Koushik Mukherjee +7
We theoretically investigate elementary excitations of dipolar quantum gases across the superfluid to supersolid phase transition in a toroidal trap. We show how decoupled first so…
