Critical coupling and in three-dimensional theory
Stephan Durr, Tolga S. H. Kiel
We consider the theory with in three Euclidean dimensions. For a variety of self-couplings , the critical (bare) parameter $\hatμ_{0\mathrm{c}}^2(\…
Diagonal Kenney-Laub Rational Approximation to the Overlap Operator using Wilson and Brillouin Kernel
Stephan Durr, Stylianos Gregoriou, Giannis Koutsou
We propose a formulation of the overlap Dirac operator in lattice QCD that employs diagonal Kenney-Laub (KL) iterates to approximate the matrix sign function. KL iterates require n…
One-loop for Wilson and Brillouin fermions with stout smearing or Wilson flow
Maximilian Ammer, Stephan Durr
We present results for the one-loop value of the improvement coefficient for Wilson and Brillouin fermions subject to stout smearing or Wilson flow, in combination…
Diagonal Kenney-Laub Rational Approximation to the Overlap Dirac Operator
Stephan Durr, Stylianos Gregoriou, Giannis Koutsou
We propose a practical formulation of the overlap Dirac operator in lattice QCD that employs the diagonal Kenney-Laub rational iterates - expressed via their partial fraction decom…
Critical coupling in theory
Stephan Durr, Tolga S. H. Kiel
We consider theory with in two Euclidean dimensions. We determine for a variety of self-couplings the (negative) critical bare mass $\hatμ_{0\math…
Optimizing decoherence in the generation of optical Schrödinger cat states
Hendrik Hegels, Thomas Stolz, Gerhard Rempe +1
We propose to use cavity Rydberg electromagnetically induced transparency to generate Schrödinger cat states of optical photons. We predict that this should make it possible to gen…
