Locality of staggered overlap operators
Nuha Chreim, Christian Hoelbling, Christian Zielinski
We give an explicit proof for the locality of staggered overlap operators. The proof covers the original two flavor construction by Adams as well as a single flavor version. As in…
Theoretical and Computational Aspects of New Lattice Fermion Formulations
Christian Zielinski
In this work we investigate theoretical and computational aspects of novel lattice fermion formulations for the simulation of lattice gauge theories. The lattice approach to quantu…
Staggered domain wall fermions
Christian Hoelbling, Christian Zielinski
We construct domain wall fermions with a staggered kernel and investigate their spectral and chiral properties numerically in the Schwinger model. In some relevant cases we see an…
Spectral properties and chiral symmetry violations of (staggered) domain wall fermions in the Schwinger model
Christian Hoelbling, Christian Zielinski
We follow up on a suggestion by Adams and construct explicit domain wall fermion operators with staggered kernels. We compare different domain wall formulations, namely the standar…
Simple QED- and QCD-like Models at Finite Density
Jan M. Pawlowski, Ion-Olimpiu Stamatescu, Christian Zielinski
In this paper we discuss one-dimensional models reproducing some features of quantum electrodynamics and quantum chromodynamics at nonzero density and temperature. Since a severe s…
Continuum limit of the axial anomaly and index for the staggered overlap Dirac operator: An overview
David H. Adams, Reetabrata Har, Yiyang Jia +1
Evaluation of the continuum limit of the axial anomaly and index is sketched for the staggered overlap Dirac operator. There are new complications compared to the usual overlap cas…
Computational efficiency of staggered Wilson fermions: A first look
David H. Adams, Daniel Nogradi, Andrii Petrashyk +1
Results on the computational efficiency of 2-flavor staggered Wilson fermions compared to usual Wilson fermions in a quenched lattice QCD simulation on lattice at $β…
Thirring model at finite density in 2+1 dimensions with stochastic quantization
Jan M. Pawlowski, Christian Zielinski
We consider a generalization of the Thirring model in 2+1 dimensions at finite density. We employ stochastic quantization and check for the applicability in the finite density case…
Thirring model at finite density in 0+1 dimensions with stochastic quantization: Crosscheck with an exact solution
Jan M. Pawlowski, Christian Zielinski
We consider a generalized Thirring model in 0+1 dimensions at finite density. In order to deal with the resulting sign problem we employ stochastic quantization, i.e., a complex La…
Entanglement Efficiencies in PT-Symmetric Quantum Mechanics
Christian Zielinski, Qing-hai Wang
The degree of entanglement is determined for an arbitrary state of a broad class of PT-symmetric bipartite composite systems. Subsequently we quantify the rate with which entangled…
