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…
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…
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…
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…
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…
Examining the quantum signatures of optimal excitation energy transfer
Jonah S. Peter, Raphael Holzinger, Stefan Ostermann +1
Light-harvesting via the transport and trapping of optically-induced electronic excitations is of fundamental interest to the design of new energy efficient quantum technologies. U…
Scaling law for Kasha's rule in photoexcited molecular aggregates
Raphael Holzinger, Nico S. Bassler, Helmut Ritsch +1
We study the photophysics of molecular aggregates from a quantum optics perspective, with emphasis on deriving scaling laws for the fast non-radiative relaxation of collective elec…
Optical Properties of Concentric Nanorings of Quantum Emitters
Verena Scheil, Raphael Holzinger, Maria Moreno-Cardoner +1
A ring of sub-wavelength spaced dipole-coupled quantum emitters features extraordinary optical properties when compared to a one-dimensional chain or a random collection of emitter…
Control of Localized Multiple Excitation Dark States in Waveguide QED
Raphael Holzinger, Ricardo Gutierrez-Jauregui, Teresa Hönigl-Decrinis +3
Subradiant excited states in finite chains of two-level quantum emitters coupled to a one-dimensional reservoir are a resource for superior photon storage and controlled photon man…
Cooperative subwavelength molecular quantum emitter arrays
Raphael Holzinger, Sue Ann Oh, Michael Reitz +2
Dipole-coupled subwavelength quantum emitter arrays respond cooperatively to external light fields as they may host collective delocalized excitations (a form of excitons) with sup…
Nanoscale continuous quantum light sources based on driven dipole emitter arrays
Raphael Holzinger, Mariona Moreno-Cardoner, Helmut Ritsch
Regular arrays of two-level emitters at distances smaller that the transition wavelength collectively scatter, absorb and emit photons. The strong inter-particle dipole coupling cr…
Subradiance in Multiply Excited States of Dipole-Coupled V-Type Atoms
Raphael Holzinger, Laurin Ostermann, Helmut Ritsch
We generalize the theoretical modeling of collective atomic super- and subradiance to the multilevel case including spontaneous emission from several excited states towards a commo…
