Deterministic spin-photon entanglement from a trapped ion in a fiber Fabry-Perot cavity

Pascal Kobel, Moritz Breyer, Michael Köhl

The development of efficient network nodes is a key element for the realisation of quantum networks which promise great capabilities as distributed quantum computing or provable se…

Pair correlations in the attractive Hubbard model

C. F. Chan, M. Gall, N. Wurz +1

The mechanism of fermionic pairing is the key to understanding various phenomena such as high-temperature superconductivity and the pseudogap phase in cuprate materials. We study t…

Simulating a Mott insulator using attractive interaction

M. Gall, C. F. Chan, N. Wurz +1

We study the particle-hole symmetry in the Hubbard model using ultracold fermionic atoms in an optical lattice. We demonstrate the mapping between charge and spin degrees of freedo…

Correlated photon-pair generation in a liquid-filled microcavity

Felix Rönchen, Thorsten F. Langerfeld, Michael Köhl

We report on the realization of a liquid-filled optical microcavity and demonstrate photon-pair generation by spontaneous four-wave mixing. The bandwidth of the emitted photons is…

Ultraviolet Fabry-Perot cavity with stable finesse under ultrahigh vacuum conditions

Jonas Schmitz, Hendrik M. Meyer, Michael Köhl

We have constructed an apparatus containing a linear ion trap and a high-finesse optical cavity in the ultraviolet spectral range. In our construction, we have avoided all organic…

Cavity-induced back-action in Purcell-enhanced photoemission of a single ion in an ultraviolet fiber-cavity

T. G. Ballance, H. M. Meyer, P. Kobel +3

We study the behavior of a single laser-driven trapped ion inside a microscopic optical Fabry-Perot cavity. In particular, we demonstrate a fiber Fabry-Perot cavity operating on th…
