Adiabatic elimination for ensembles of emitters in cavities with dissipative couplings
David Hagenmüller, Stefan Schütz, Guido Pupillo +1
We consider an ensemble of cavity-coupled two-level emitters interacting via full (coherent and dissipative) dipole-dipole interactions. Using an adiabatic elimination procedure we…
Dynamics of rotated spin states and magnetic ordering with two-component bosonic atoms in optical lattices
Araceli Venegas-Gomez, Anton S. Buyskikh, Johannes Schachenmayer +2
The microscopic control available over cold atoms in optical lattices has opened new opportunities to study the properties of quantum spin models. While a lot of attention is focus…
Collective Excitation Dynamics of a Cold Atom Cloud
T. S. do Espirito Santo, P. Weiss, A. Cipris +4
We study the time-dependent response of a cold atom cloud illuminated by a laser beam immediately after the light is switched on experimentally and theoretically. We show that coop…
Doublon dynamics of Bose-Fermi mixtures in optical lattices
Martin Gärttner, Arghavan Safavi-Naini, Johannes Schachenmayer +1
We study the out-of-equilibrium dynamics of a dilute, lattice-confined Bose-Fermi mixture initialized in a highly excited state consisting of boson-fermion pairs (doublons) occupyi…
A generalized phase space approach for solving quantum spin dynamics
Bihui Zhu, Ana Maria Rey, Johannes Schachenmayer
Numerical techniques to efficiently model out-of-equilibrium dynamics in interacting quantum many-body systems are key for advancing our capability to harness and understand comple…
Ensemble-induced strong light-matter coupling of a single quantum emitter
Stefan Schütz, Johannes Schachenmayer, David Hagenmüller +6
We discuss a technique to strongly couple a single target quantum emitter to a cavity mode, which is enabled by virtual excitations of a nearby mesoscopic ensemble of emitters. A c…
