Ultracold Feshbach molecules in an orbital optical lattice
Yann Kiefer, Max Hachmann, Andreas Hemmerich
Quantum gas systems provide a unique experimental platform to study a fundamental paradigm of quantum many-body physics: the crossover between Bose-Einstein condensed (BEC) molecul…
Condensate formation in a dark state of a driven atom-cavity system
Jim Skulte, Phatthamon Kongkhambut, Sahana Rao +4
We demonstrate condensate formation in a dark state in an ultracold quantum gas coupled to a high-finesse cavity and pumped by a shaken optical lattice. We show experimentally and…
Experimental realization of a high precision tunable hexagonal optical lattice
Jin-Yu Liu, Guang-Quan Luo, Xiao-Qiong Wang +2
Hexagonal optical lattices offer a tunable platform to study exotic orbital physics in solid state materials. Here, we present a versatile high-precision scheme to implement a hexa…
Route towards classical frustration and band flattening via optical lattice distortion
Pil Saugmann, José Vargas, Yann Kiefer +4
We propose and experimentally explore a method for realizing frustrated lattice models using a Bose-Einstein condensate held in an optical square lattice. A small lattice distortio…
Observation of a continuous time crystal
Phatthamon Kongkhambut, Jim Skulte, Ludwig Mathey +3
Time crystals are classified as discrete or continuous depending on whether they spontaneously break discrete or continuous time translation symmetry. While discrete time crystals…
Realization of a periodically driven open three-level Dicke model
Phatthamon Kongkhambut, Hans Keßler, Jim Skulte +3
A periodically driven open three-level Dicke model is realized by resonantly shaking the pump field in an atom-cavity system. As an unambiguous signature, we demonstrate the emerge…
