First Simulation Results for the Photon in a Non-Commutative Space
W. Bietenholz, F. Hofheinz, J. Nishimura +2
We present preliminary simulation results for QED in a non-commutative 4d space-time, which is discretized to a fuzzy lattice. Its numerical treatment becomes feasible after its ma…

Phase diagram and dispersion relation of the non-commutative λϕ^{4} model in d=3
W. Bietenholz, F. Hofheinz, J. Nishimura
We present a non-perturbative study of the λϕ^{4} model in a three dimensional Euclidean space, where the two spatial coordinates are non-commutative. Our results are obtained from…
