Topologically non-trivial field configurations - interplay of vortices and Dirac eigenmodes
Stefan Solbrig, Jochen Gattnar, Christof Gattringer +4
Gluon field configurations with non-trivial topology like instantons, magnetic monopoles and center vortices play a crucial role in QCD and, in particular, for the spontaneous brea…
Implementing Hybrid Monte Carlo with stout-smeared chirally improved Dirac operators
C. B. Lang, Pushan Majumdar, Wolfgang Ortner
We discuss our implementation of dynamical Ginsparg-Wilson type fermions using a stout-smeared chirally improved Dirac operator. Such operators have been studied extensively in que…
Spin properties of single electron states in coupled quantum dots
Peter Stano, Jaroslav Fabian
Spin properties of single electron states in laterally coupled quantum dots in the presence of a perpendicular magnetic field are studied by exact numerical diagonalization. Dresse…
Quantum chaos in QCD and hadrons
Harald Markum, Willibald Plessas, Rainer Pullirsch +2
This article is the written version of a talk delivered at the Workshop on Nonlinear Dynamics and Fundamental Interactions in Tashkent and starts with an introduction into quantum…
Influence of Pressure on the Structure and Electronic Properties of the Layered Superconductor Y2C2I2
Kyungsoo Ahn, Reinhard K. Kremer, Arndt Simon +3
The structural properties under hydrostatic pressure up to 3 GPa of the layered rare earth carbide halide superconductor Y2C2I2 are studied by neutron powder diffraction at room te…
Entanglement distillation by adiabatic passage in coupled quantum dots
Jaroslav Fabian, Ulrich Hohenester
Adiabatic passage of two correlated electrons in three coupled quantum dots is shown to provide a robust and controlled way of distilling, transporting and detecting spin entanglem…
