Conditional Entanglement Amplification via Non-Hermitian Superradiant Dynamics
Christoph Hotter, Arkadiusz Kosior, Helmut Ritsch +1
Due to the inherently probabilistic nature of quantum mechanics, each experimental realization of a dynamical quantum system may yield a different measurement outcome, especially w…
Symmetry based efficient simulation of dissipative quantum many-body dynamics in subwavelength quantum emitter arrays
Raphael Holzinger, Oriol Rubies-Bigorda, Susanne F. Yelin +1
We propose an efficient method to numerically simulate the dissipative dynamics of large numbers of quantum emitters in ordered arrays in the presence of long-range dipole-dipole i…
Self-ordering, cooling, and lasing in an ensemble of clock atoms
Anna Bychek, Laurin Ostermann, Helmut Ritsch
Active atomic clocks are predicted to provide far better short-term stability and robustness against thermal fluctuations than typical feedback-based optical atomic clocks. However…
Subradiance and Superradiant Long Range Excitation Transport among Quantum Emitter Ensembles in a Waveguide
Martin Fasser, Laurin Ostermann, Helmut Ritsch +1
In contrast to free space, in waveguides the dispersive and dissipative dipole-dipole interactions among quantum emitters exhibit a periodic behavior over remarkably long distances…
Collectively enhanced ground-state cooling in subwavelength atomic arrays
Oriol Rubies-Bigorda, Raphael Holzinger, Ana Asenjo-Garcia +6
Subwavelength atomic arrays feature strong light-induced dipole-dipole interactions, resulting in subradiant collective resonances characterized by narrowed linewidths. In this wor…
