Gauge theories on a five-dimensional orbifold
Francesco Knechtli, Burkhard Bunk, Nikos Irges
We present a construction of non-Abelian gauge theories on the R^4 x S^1/Z_2 orbifold. We show that no divergent boundary mass term for the Higgs field, identified with some of the…
The locality problem for two tastes of staggered fermions
B. Bunk, M. Della Morte, K. Jansen +1
We address the locality problem arising in simulations, which take the square root of the staggered fermion determinant as a Boltzmann weight to reduce the number of dynamical quar…
Locality with staggered fermions
B. Bunk, M. Della Morte, K. Jansen +1
We address the locality problem arising in simulations, which take the square root of the staggered fermion determinant as a Boltzmann weight to reduce the number of dynamical quar…
Compact QED under scrutiny: it's first order
G. Arnold, B. Bunk, Th. Lippert +1
We report new results from our finite size scaling analysis of 4d compact pure U(1) gauge theory with Wilson action. Investigating several cumulants of the plaquette energy within…
Fractional Inversion in Krylov Space
B. Bunk
The fractional inverse (real ) of a matrix is expanded in a series of Gegenbauer polynomials. If the spectrum of is confined to an ellipse not including the o…
Ordering monomial factors of polynomials in the product representation
B. Bunk, S. Elser, R. Frezzotti +1
The numerical construction of polynomials in the product representation (as used for instance in variants of the multiboson technique) can become problematic if rounding errors ind…
