Collective rotational cat states of molecules in microwave cavities
Volker Karle, Florian Kluibenschedl, Mikhail Lemeshko +1
We show theoretically that an ensemble of polar molecules coupled to a microwave cavity supports hybrid rotational-photonic cat states. The cavity couples to a symmetric rotor in t…

Anomalous multi-gap topological phases in periodically driven quantum rotors
Volker Karle, Mikhail Lemeshko, Adrien Bouhon +2
We demonstrate that periodically driven quantum rotors provide a promising and broadly applicable platform to implement multi-gap topological phases, where groups of bands can acqu…
