Application of Contractor Renormalization Group (CORE) to the Heisenberg zig-zag and the Hubbard chain
Krzysztof Cichy, Piotr Tomczak
The COntractor REnormalization group method was devised in 1994 by Morningstar and Weinstein. It was primarily aimed at extracting the physics of lattice quantum field theories (li…

Twisted Mass, Overlap and Creutz Fermions: Cut-off Effects at Tree-level of Perturbation Theory
K. Cichy, J. Gonzalez Lopez, K. Jansen +2
We study cutoff effects at tree-level of perturbation theory for maximally twisted mass Wilson, overlap and the recently proposed Creutz fermions. We demonstrate that all three kin…
