Continuous Narrow-Linewidth Superradiance in Waveguide QED
Anna Bychek, Martin Fasser, Ivan Vybornyi +4
Superradiant lasers promise continuous, narrow-linewidth coherent emission at the bare atomic transition frequency, enabling frequency references of exceptional precision. Recent e…

Nanoscale Mirrorless Superradiant Lasing
Anna Bychek, Raphael Holzinger, Helmut Ritsch
We predict collective 'free-space' lasing in a dense nanoscopic emitter arrangement where dipole-dipole coupled atomic emitters synchronize their emission and exhibit lasing behavi…

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…
