Selective protected state preparation of coupled dissipative quantum emitters

D Plankensteiner, L Ostermann, H Ritsch, C Genes - Scientific reports, 2015 - nature.com
Inherent binary or collective interactions in ensembles of quantum emitters induce a spread
in the energy and lifetime of their eigenstates. While this typically causes fast decay and …

Optimized geometries for future generation optical lattice clocks

S Krämer, L Ostermann, H Ritsch - Europhysics Letters, 2016 - iopscience.iop.org
Atoms deeply trapped in magic wavelength optical lattices provide a Doppler-and collision-
free dense ensemble of quantum emitters ideal for high-precision spectroscopy and they are …

Collective radiation of coupled atomic dipoles and the precise measurement of time

L Ostermann - 2016 - inis.iaea.org
Ultracold optical lattice atomic clocks have made it to the forefront of timekeeping and
spectroscopy over the last decade. A prominent example, that features a relative precision of …
