Automatic generation of Feynman rules in the Schroedinger functional
Shinji Takeda
We provide an algorithm to generate vertices for the Schrödinger functional with an abelian background gauge field. The background field has a non-trivial color structure, therefor…
On cutoff effects in lattice QCD from short to long distances
Michele Della Morte, Rainer Sommer, Shinji Takeda
We discuss kinematical enhancements of cutoff effects at short and intermediate distances. Starting from a pedagogical example with periodic boundary conditions, we switch to the c…
Scaling test of two-flavor O(a)-improved lattice QCD
Michele Della Morte, Patrick Fritzsch, Harvey B. Meyer +5
We report on a scaling test of several mesonic observables in the non-perturbatively O(a) improved Wilson theory with two flavors of dynamical quarks. The observables are construct…
Perturbative analysis of the Neuberger-Dirac operator in the Schrödinger functional
Shinji Takeda
We investigate the spectrum of the free Neuberger-Dirac operator $\Dov$ on the Schrödinger functional (SF). We check that the lowest few eigen-values of the Hermitian operator $\Do…
Spectral properties of the non-hermitian Wilson-Dirac operator in the Schroedinger functional
Oliver Witzel, Shinji Takeda, Ulli Wolff
We report on some preparatory investigations for the simulation of the QCD Schroedinger functional with a non-hermitian polynomial hybrid Monte Carlo algorithm. The complex spectru…
Automatic generation of vertices for the Schroedinger functional
Shinji Takeda, Ulli Wolff
We present a multiplication algorithm to recursively construct vertices for the Schroedinger functional in the abelian background field case. The algorithm is suited for automatic…
