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…

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…

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…
