Nonequilibrium Nonlinear Effects and Dynamical Boson Condensation in a Driven-Dissipative Wannier-Stark Lattice
Arkadiusz Kosior, Karol Gietka, Farokh Mivehvar +1
Driven-dissipative light-matter systems can exhibit collective nonequilibrium phenomena due to loss and gain processes on the one hand and effective photon-photon interactions on t…
Combining critical and quantum metrology
Christoph Hotter, Helmut Ritsch, Karol Gietka
Critical metrology relies on the precise preparation of a system in its ground state near a quantum phase transition point where quantum correlations get very strong. Typically thi…
Threshold studies for a hot beam superradiant laser including an atomic guiding potential
Martin Fasser, Christoph Hotter, David Plankensteiner +1
Recent theoretical predictions hint at an implementation of a superradiant laser based on narrow optical clock transitions by using a filtered thermal beam at high density. Corresp…
Collectively enhanced Ramsey readout by cavity sub- to superradiant transition
Eliot Bohr, Sofus L. Kristensen, Christoph Hotter +6
When an inverted ensemble of atoms is tightly packed on the scale of its emission wavelength or when the atoms are collectively strongly coupled to a single cavity mode, their dipo…
Tuning photon-mediated interactions in a multimode cavity: from supersolid to insulating droplets hosting phononic excitations
Natalia Masalaeva, Helmut Ritsch, Farokh Mivehvar
Ultracold atoms trapped in laser-generated optical lattices serve as a versatile platform for quantum simulations. However, as these lattices are infinitely stiff, they do not allo…
Unique Steady-State Squeezing in a Driven Quantum Rabi Model
Karol Gietka, Christoph Hotter, Helmut Ritsch
Squeezing is essential to many quantum technologies and our understanding of quantum physics. Here we develop a theory of steady-state squeezing that can be generated in the closed…
