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…
