Polarization Control of Radiation and Energy Flow in Dipole-Coupled Nanorings
Julian Cremer, David Plankensteiner, Mariona Moreno-Cardoner +2
Collective optical excitations in dipole-coupled nanorings of sub-wavelength spaced quantum emitters exhibit extreme sub-radiance and field confinement facilitating an efficient an…
Superradiant Cooling, Trapping, and Lasing of Dipole-Interacting Clock Atoms
Christoph Hotter, David Plankensteiner, Laurin Ostermann +1
A cold atomic gas with an inverted population on a transition coupled to a field mode of an optical resonator constitutes a generic model of a laser. For quasi-continuous operation…
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…
Extraordinary subradiance with lossless excitation transfer in dipole-coupled nano-rings of quantum emitters
Maria Moreno-Cardoner, David Plankensteiner, Laurin Ostermann +2
A ring of sub-wavelength spaced dipole-coupled quantum emitters possesses only few radiant but many extraordinarily subradiant collective modes. These exhibit a 3D-confined spatial…
Super- and subradiance of clock atoms in multimode optical waveguides
Laurin Ostermann, Clement Meignant, Claudiu Genes +1
The transversely confined propagating modes of an optical fiber mediate virtually infinite range energy exchanges among atoms placed within their field, which adds to the inherent…
