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…
