Flavor blindness and patterns of flavor symmetry breaking in lattice simulations of up, down, and strange quarks
- W. Bietenholz, V. Bornyakov, J. Zanotti
- Physics
- 25 February 2011
QCD lattice simulations with 2+1 flavours (when two quark flavours are mass degenerate) typically start at rather large up-down and strange quark masses and extrapolate first the strange quark mass…

A non-perturbative study of 4d U(1) non-commutative gauge theory — the fate of one-loop instability

Recent perturbative studies show that in 4d non-commutative spaces, the trivial (classically stable) vacuum of gauge theories becomes unstable at the quantum level, unless one introduces sufficiently…
PERFECT SCALARS ON THE LATTICE

We perform renormalization group transformations to construct optimally local perfect lattice actions for free scalar fields of any mass. Their couplings decay exponentially. The spectrum is…
Monte Carlo studies of the IIB matrix model at large N
- J. Ambjorn, K. Anagnostopoulos, W. Bietenholz, T. Hotta, J. Nishimura
- Physics
- 16 May 2000
The low-energy effective theory of the IIB matrix model developed by H. Aoki et al. is written down explicitly in terms of bosonic variables only. The effective theory is then studied by Monte Carlo…
Large N dynamics of dimensionally reduced 4D SU(N) super Yang-Mills theory
- J. Ambjorn, K. Anagnostopoulos, W. Bietenholz, T. Hotta, J. Nishimura
- Physics
- 23 March 2000
We perform Monte Carlo simulations of a supersymmetric matrix model, which is obtained by dimensional reduction of 4D SU(N) super Yang-Mills theory. The model can be considered as a four-dimensional…
Exploring the nucleon structure from first principles of QCD
- W. Bietenholz, N. Cundy, J. Zanotti
- Physics
- 13 April 2010
Quantum Chromodynamics (QCD) is generally assumed to be the fundamental theory underlying nuclear physics. In recent years there is progress towards investigating the nucleon structure from first…

Topological lattice actions
- W. Bietenholz, U. Gerber, M. Pepe, U. Wiese
- Physics
- 11 September 2010
We consider lattice field theories with topological actions, which are invariant against small deformations of the fields. Some of these actions have infinite barriers separating different…
