How compactness curbs entanglement growth in bosonic systems
Stefan Aimet, Philipp Schmoll, Jens Eisert +2
Zero modes, understood here as degrees of freedom with vanishing confining frequency, play a central role in the nonequilibrium dynamics of bosonic systems. In Gaussian models, how…
Tachyonic and parametric instabilities in an extended bosonic Josephson junction
Laura Batini, Sebastian Erne, Jörg Schmiedmayer +1
We study the dynamics and decay of quantum phase coherence for Bose-Einstein condensates in tunnel-coupled quantum wires. The two elongated Bose-Einstein condensates exhibit a wide…
Optimizing magnetic coupling in lumped element superconducting resonators for molecular spin qubits
Marcos RubÃn-Osanz, David Rodriguez, Ignacio Gimeno +18
We engineer lumped-element superconducting resonators that maximize magnetic coupling to molecular spin qubits, achieving record single-spin couplings up to kHz and collectiv…
Self-Induced Superradiant Masing
Wenzel Kersten, Nikolaus de Zordo, Oliver Diekmann +9
In cavity quantum electrodynamics (cQED) and particularly superradiance, emitters are typically assumed to be independent, interacting only through light shared via a common mode.…
