A comparison of the cut-off effects for Twisted Mass, Overlap and Creutz fermions at tree-level of Perturbation Theory
Krzysztof Cichy, Jenifer Gonzalez Lopez, Agnieszka Kujawa
In this paper we investigate the cutoff effects at tree-level of perturbation theory for three different lattice regularizations of fermions -- maximally twisted mass Wilson, overl…
Some Properties of the Spin-Polarized Attractive Hubbard Model
Agnieszka Kujawa, Roman Micnas
The influence of a Zeeman magnetic field on the superconducting characteristics of the attractive Hubbard model was investigated. The ground state and temperature phase diagrams we…
On the Phase Diagram of Spin-Polarized Attractive Hubbard Model: Weak Coupling Limit
Agnieszka Kujawa, Roman Micnas
The superfluid properties of the attractive Hubbard model in a Zeeman magnetic field, and in the weak coupling regime have been investigated. The temperature and magnetic field dep…
The BCS-BEC crossover and superconductivity in a lattice fermion model with hard core repulsion
Agnieszka Kujawa
We have considered the BCS-BEC crossover at T=0 in the framework of a lattice fermion model (the extended Hubbard model). We have analyzed the case of on-site hard core repulsion (…
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…
Cutoff effects for Wilson twisted mass fermions 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 standard Wilson and Wilson twisted mass fermionic lattice actions with Nf=2 flavour degenerate quarks. The discreti…
