Flavor blindness and patterns of flavor symmetry breaking in lattice simulations of up, down, and strange quarks

- W. Bietenholz, V. Bornyakov,
+12 authors 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… Expand

Tuning the strange quark mass in lattice simulations

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

- W. Bietenholz, J. Nishimura, Y. Susaki, J. Volkholz
- Physics
- 11 August 2006

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… Expand

PERFECT SCALARS ON THE LATTICE

- W. Bietenholz
- Physics
- 11 November 1999

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… Expand

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… Expand

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… Expand

Exploring the nucleon structure from first principles of QCD

- W. Bietenholz, N. Cundy,
+8 authors 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… Expand

CP(N-1) Quantum Field Theories with Alkaline-Earth Atoms in Optical Lattices

- C. Laflamme, W. Evans,
+5 authors P. Zoller - Physics
- 24 July 2015

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… Expand
