Effective chiral restoration in the rho'-meson in lattice QCD
L. Ya. Glozman, C. B. Lang, M. Limmer
In simulations with dynamical quarks it has been established that the ground state rho in the infrared is a strong mixture of the two chiral representations (0,1)+(1,0) and (1/2,1/…
Lattice study of light scalar tetraquarks with I=0,2,1/2,3/2: are sigma and kappa tetraquarks?
S. Prelovsek, T. Draper, C. B. Lang +4
We investigate whether the lightest scalar mesons sigma and kappa have a large tetraquark component, as is strongly supported by many phenomenological studies. A search for possibl…
Control and Tomography of a Three Level Superconducting Artificial Atom
R. Bianchetti, S. Filipp, M. Baur +6
A number of superconducting qubits, such as the transmon or the phase qubit, have an energy level structure with small anharmonicity. This allows for convenient access of higher ex…
Quantum-to-Classical Transition in Cavity Quantum Electrodynamics
J. M. Fink, L. Steffen, P. Studer +8
The quantum properties of electromagnetic, mechanical or other harmonic oscillators can be revealed by investigating their strong coherent coupling to a single quantum two level sy…
Measurements of the Correlation Function of a Microwave Frequency Single Photon Source
D. Bozyigit, C. Lang, L. Steffen +8
At optical frequencies the radiation produced by a source, such as a laser, a black body or a single photon source, is frequently characterized by analyzing the temporal correlatio…
Searching for tetraquarks on the lattice
S. Prelovsek, T. Draper, C. B. Lang +4
We address the question whether the lightest scalar mesons sigma and kappa are tetraquarks. We present a search for possible light tetraquark states with J^PC=0^++ and I=0, 1/2, 3/…
