Optical centrifuge as a probe of strong dissipative coupling between a molecular rotor and superfluid helium
Ian MacPhail-Bartley, Sören E. Mahr, Cameron E. Peters +7
A macroscopic manifestation of superfluidity is that objects moving through liquid helium experience negligible friction below the Landau critical velocity. How this frictionless m…
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…
Hybrid light-matter boundaries of graphene in a chiral cavity
Volker Karle, Oriana K. Diessel, Vasil Rokaj +1
Recent advances in chiral cavities that can couple coherently to two-dimensional materials have opened a powerful route to reshape electronic topology without an external drive. He…
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…
Modeling laser pulses as -kicks: reevaluating the impulsive limit in molecular rotational dynamics
Volker Karle, Mikhail Lemeshko
The impulsive limit (the "sudden approximation") has been widely employed to describe the interaction between molecules and short, far-off-resonant laser pulses. This approximation…
Topological charges of periodically kicked molecules
Volker Karle, Areg Ghazaryan, Mikhail Lemeshko
We show that the simplest of existing molecules -- closed-shell diatomics not interacting with one another -- host topological charges when driven by periodic far-off-resonant lase…
Area-law entangled eigenstates from nullspaces of local Hamiltonians
Volker Karle, Maksym Serbyn, Alexios A. Michailidis
Eigenstate thermalization in quantum many-body systems implies that eigenstates at high energy are similar to random vectors. Identifying systems where at least some eigenstates ar…
Emergence of cascading dynamics in interacting tipping elements of ecology and climate
Ann Kristin Klose, Volker Karle, Ricarda Winkelmann +1
In ecology, climate and other fields, (sub)systems have been identified that can transition into a qualitatively different state when a critical threshold or tipping point in a dri…
Coupled superfluidity of binary Bose mixtures in two dimensions
Volker Karle, Nicolo Defenu, Tilman Enss
We consider a two-component Bose gas in two dimensions at low temperature with short-range repulsive interaction. In the coexistence phase where both components are superfluid, int…
Classical dynamical localization
Italo Guarneri, Giulio Casati, Volker Karle
We consider classical models of the kicked rotor type, with piecewise linear kicking potentials designed so that momentum changes only by multiples of a given constant. Their dynam…
