Superabsorption of light via quantum engineering [PDF]
, 2014 Almost 60 years ago Dicke introduced the term superradiance to describe a signature quantum effect: N atoms can collectively emit light at a rate proportional to N-2.

Monte-Carlo simulations of superradiant lasing
New Journal of Physics, 2018 We simulate the superradiant dynamics of ensembles of atoms in the presence of collective and individual atomic decay processes. We apply the Monte-Carlo wave-function method and identify quantum jumps in a reduced Dicke state basis, which reflects the ...

Results in Physics, 2021 We mainly investigate Dicke phase transition at finite temperature in an optomechanical-atomic cavity by means of the functional path-integral approach. By the thermodynamic equilibrium equation, the mean photon number, the scaled atomic population, the ...

Quantum metrology with Dicke squeezed states
New Journal of Physics, 2014 We introduce a new class of quantum many-particle entangled states, called the Dicke squeezed (or DS) states, which can be used to improve the precision in quantum metrology beyond the standard quantum limit.

Ising model in a light-induced quantized transverse field
Physical Review Research, 2020 We investigate the influence of light-matter interactions on correlated quantum matter by studying the paradigmatic Dicke-Ising model. This type of coupling to a confined, spatially delocalized bosonic light mode, such as provided by an optical resonator,

Superradiant to subradiant phase transition in the open system Dicke model: dark state cascades
New Journal of Physics, 2018 Collectivity in ensembles of atoms gives rise to effects like super- and subradiance. While superradiance is well studied and experimentally accessible, subradiance remains elusive since it is difficult to track experimentally as well as theoretically ...

Universality of Dicke superradiance in arrays of quantum emitters
Nature Communications, 2022 Dicke superradiance is an important collective quantum phenomenon, but its analysis is hindered by the exponential growth of the state space with atom number.

Detecting metrologically useful entanglement in the vicinity of Dicke states
New Journal of Physics, 2015 We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measurement of the sensitivity.

Experimental realization of the classical Dicke model
Physical Review Research, 2020 We report the experimental implementation of the classical description of the Dicke model whose quantum version describes a large number of two-level atoms interacting with a single-mode electromagnetic field in a perfectly reflecting cavity.

Glutaredoxine reduzieren schnell Glutathionhydroper‐ und Glutathionpolysulfide
Angewandte Chemie, EarlyView.Glutaredoxine (Grx) reduzieren Glutathionpolysulfide (GSSnSG) schnell zu Glutathionhydroper/polysulfiden (GSSnH) oder GSSnH zu Wasserstoff(poly)sulfiden (H2Sn). Die Reduktion glutathionylierter Grx durch reduziertes Glutathion (GSH) liefert Glutathiondisulfid (GSSG).
