Enhancement of Rydberg-mediated single-photon nonlinearities by electrically tuned Förster resonances.

Nature communications

Gorniaczyk H, Tresp C, Bienias P, Paris-Mandoki A, Li W, Mirgorodskiy I, Büchler HP, Lesanovsky I, Hofferberth S.
PMID: 27515278
Nat Commun. 2016 Aug 12;7:12480. doi: 10.1038/ncomms12480.

Mapping the strong interaction between Rydberg atoms onto single photons via electromagnetically induced transparency enables manipulation of light at the single-photon level and few-photon devices such as all-optical switches and transistors operated by individual photons. Here we demonstrate experimentally...

First experimental evidence for chaos-assisted tunneling in a microwave annular billiard.

Physical review letters

Dembowski C, Graf H, Heine A, Hofferbert R, Rehfeld H, Richter A.
PMID: 11017392
Phys Rev Lett. 2000 Jan 31;84(5):867-70. doi: 10.1103/PhysRevLett.84.867.

We report on first experimental signatures for chaos-assisted tunneling in a two-dimensional annular billiard. Measurements of microwave spectra from a superconducting cavity with high frequency resolution are combined with electromagnetic field distributions experimentally determined from a normal conducting twin...

Non-equilibrium coherence dynamics in one-dimensional Bose gases.

Nature

Hofferberth S, Lesanovsky I, Fischer B, Schumm T, Schmiedmayer J.
PMID: 17882216
Nature. 2007 Sep 20;449(7160):324-7. doi: 10.1038/nature06149.

Low-dimensional systems provide beautiful examples of many-body quantum physics. For one-dimensional (1D) systems, the Luttinger liquid approach provides insight into universal properties. Much is known of the equilibrium state, both in the weakly and strongly interacting regimes. However, it...

Weakly interacting Bose gas in the one-dimensional limit.

Physical review letters

Krüger P, Hofferberth S, Mazets IE, Lesanovsky I, Schmiedmayer J.
PMID: 21231675
Phys Rev Lett. 2010 Dec 31;105(26):265302. doi: 10.1103/PhysRevLett.105.265302. Epub 2010 Dec 28.

We prepare a chemically and thermally one-dimensional (1D) quantum degenerate Bose gas in a single microtrap. We introduce a new interferometric method to distinguish the quasicondensate fraction of the gas from the thermal cloud at finite temperature. We reach...

Photon Subtraction by Many-Body Decoherence.

Physical review letters

Murray CR, Mirgorodskiy I, Tresp C, Braun C, Paris-Mandoki A, Gorshkov AV, Hofferberth S, Pohl T.
PMID: 29601756
Phys Rev Lett. 2018 Mar 16;120(11):113601. doi: 10.1103/PhysRevLett.120.113601.

We experimentally and theoretically investigate the scattering of a photonic quantum field from another stored in a strongly interacting atomic Rydberg ensemble. Considering the many-body limit of this problem, we derive an exact solution to the scattering-induced spatial decoherence...

The Post-mating Switch in the Pheromone Response of .

Frontiers in behavioral neuroscience

Front Behav Neurosci. 2018 Jan 30;12:14. doi: 10.3389/fnbeh.2018.00014. eCollection 2018.

The olfactory sense is of crucial importance for animals, but their response to chemical stimuli is plastic and depends on their physiological state and prior experience. In many insect species, mating status influences the response to sex pheromones, but...

Maximization of Markers Linked in Coupling for Tetraploid Potatoes via Monoparental Haploids.

Frontiers in plant science

Bartkiewicz AM, Chilla F, Terefe-Ayana D, Lübeck J, Strahwald J, Tacke E, Hofferbert HR, Linde M, Debener T.

Front Plant Sci. 2018 May 07;9:620. doi: 10.3389/fpls.2018.00620. eCollection 2018.

Haploid potato populations derived from a single tetraploid donor constitute an efficient strategy to analyze markers segregating from a single donor genotype. Analysis of marker segregation in populations derived from crosses between polysomic tetraploids is complicated by a maximum...

Emergent Universal Dynamics for an Atomic Cloud Coupled to an Optical Waveguide.

An unprecedented high barrier to ring inversion [Eq. (1)] prevents 1 from engaging in bifacial complexation with lithium ions. The X-ray crystal structure analysis of this hexaspiro compound corroborates the adoption of a cyclohexane chair with all six C-O...
