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…
Light-induced Self-Organization in Cooperative Free Space Atomic Arrays
Sara Molló-Guri, Oriol Rubies-Bigorda, Raphael Holzinger +2
We investigate how laser-driven, cooperative dipole-dipole interactions in weakly trapped atomic arrays give rise to self-organized configurations. Starting from an analytically tr…
Scaling of Superradiant Peak Emission in Spatially Extended Emitter Arrays
Raphael Holzinger, Susanne F. Yelin
In quantum optics, superradiance is a phenomenon in which a system of fully excited quantum emitters radiate intense flashes of light during collective decay. However, computin…
Superradiant Peak Emission Rate and Time in Quantum Emitter Arrays
Raphael Holzinger, Susanne F. Yelin
Determining the peak photon emission time and rate for an ensemble of quantum systems undergoing collective superradiant decay typically requires tracking the time evolution of…
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…
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…
