Field Theory Simulations on a Fuzzy Sphere - an Alternative to the Lattice
Julieta Medina, Wolfgang Bietenholz, Frank Hofheinz +1
We explore a new way to simulate quantum field theory, without introducing a spatial lattice. As a pilot study we apply this method to the 3d λϕ^4 model. The regularisation consist…
The Scaling of QED in a Non-Commutative Space-Time
J. Volkholz, W. Bietenholz, J. Nishimura +1
We present results of numerical simulations for pure U(1) gauge theory in a non-commutative space. The theory is mapped onto a dimensionally reduced matrix model, which renders its…
Low Energy Constants from the zero mode contribution to the pseudo-scalar correlator
S. Shcheredin, W. Bietenholz
We apply different types of overlap operators in quenched QCD simulations to compute the zero mode contribution to the pseudo-scalar correlator. In particular we use the convention…
Relating Chiral Perturbation Theory and QCD Simulations with Overlap Hypercube Fermions
W. Bietenholz, S. Shcheredin
We present simulation results for lattice QCD with light pions. For the quark fields we apply chirally symmetric lattice Dirac operators, in particular the overlap hypercube operat…
The Non-Commutative λϕ^{4} Model
W. Bietenholz, F. Hofheinz, J. Nishimura
In the recent years, field theory on non-commutative (NC) spaces has attracted a lot of attention. Most literature on this subject deals with perturbation theory, although the latt…
A Ginsparg-Wilson Approach to Lattice Chern-Simons Theory
W. Bietenholz, P. Sodano
The concept of lattice modified symmetry formulations is adapted to the parity symmetry of gauge fields and applied to the pure Abelian Chern-Simons action in three dimensions. We…
