Optical Schrödinger cat states generated using cavity Rydberg quantum photonics
Hendrik Hegels, Mae Eichenberger, Gerhard Rempe +1
We introduce cavity Rydberg quantum photonics as a novel platform for generating hybrid entangled states of optical photons. The system achieves world-record sizes of these states…
Stout smearing and Wilson flow in lattice perturbation theory
Maximilian Ammer, Stephan Durr
We present the expansion of stout smearing and the Wilson flow in lattice perturbation theory to order , which is suitable for one-loop calculations. As the Wilson flow is g…
Calculation of at one-loop order for Brillouin fermions
Maximilian Ammer, Stephan Durr
The Brillouin action is a Wilson-like lattice fermion action with a 81-point stencil, which was found to ameliorate the Wilson action in many respects. The Sheikholeslami-Wohlert c…
Topological properties of minimally doubled fermions in two space-time dimensions
Stephan Dürr, Johannes H. Weber
The two-dimensional Schwinger model is used to explore how lattice fermion operators perceive the global topological charge of a given background gauge field. We…
Quantum-Logic Gate between Two Optical Photons with an Average Efficiency above 40%
Thomas Stolz, Hendrik Hegels, Maximilian Winter +5
Optical qubits uniquely combine information transfer in optical fibers with a good processing capability and are therefore attractive tools for quantum technologies. A large challe…
FLAG Review 2021
Y. Aoki, T. Blum, G. Colangelo +34
We review lattice results related to pion, kaon, -meson, -meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communi…
On the suitability of the Brillouin action as a kernel to the overlap procedure
Stephan Durr, Giannis Koutsou
We investigate the Brillouin action in terms of its suitability as a kernel to the overlap procedure, with a view on both heavy and light quark physics. We use the diagonal element…
First numerical experiences with overlap fermions based on the Brillouin kernel
Stephan Durr, Giannis Koutsou
Numerical experiences are reported with overlap fermions which employ the Brillouin action as a kernel. After discussing the dispersion relations of both the kernel and the resulti…
Leptonic decay-constant ratio from clover-improved QCD
Enno E. Scholz, Stephan Durr
The leptonic decay-constant ratio is calculated from lattice-QCD simulations using dynamical fermion flavors in the clover-improved formulation and 2-HEX smeari…
Optical Phase Shift Created with a Single-Photon Pulse
Daniel Tiarks, Steffen Schmidt, Gerhard Rempe +1
A deterministic photon-photon quantum-logic gate is a long-standing goal. Building such a gate becomes possible if a light pulse containing only one photon imprints a phase shift o…

We present a preliminary study of the charmed meson spectra using the electrically neutral subset of the new Budapest-Marseille-Wuppertal N_f=2+1+1 gauge configurations that utilis…
Breakdown of atomic hyperfine coupling in a deep optical-dipole trap
Andreas Neuzner, Matthias Körber, Stephan Dürr +2
We experimentally study the breakdown of hyperfine coupling for an atom in a deep optical-dipole trap. One-color laser spectroscopy is performed at the resonance lines of a single…
Single-Photon Transistor Using a Förster Resonance
Daniel Tiarks, Simon Baur, Katharina Schneider +2
An all-optical transistor is a device in which a gate light pulse switches the transmission of a target light pulse with a gain above unity. The gain quantifies the change of the t…

All-optical switching is a technique in which a gate light pulse changes the transmission of a target light pulse without the detour via electronic signal processing. We take this…
Isospin splittings in the light baryon octet from lattice QCD and QED
Sz. Borsanyi, S. Dürr, Z. Fodor +11
While electromagnetic and up-down quark mass difference effects on octet baryon masses are very small, they have important consequences. The stability of the hydrogen atom against…
