Perturbative Thermodynamics of Lattice QCD with Chiral-Invariant Four-Fermion Interactions
Michael Chavel
Lattice QCD with additional chiral-invariant four-fermion interactions is studied at nonzero temperature. Staggered Kogut-Susskind quarks are used. The four-fermion interactions ar…

Finite density QCD with chiral invariant four-fermion interactions
Michael Chavel
A mean field analysis of finite density QCD is presented including the effects of additional chiral invariant four-fermion interactions. A lattice regularization is used with N_f=4…

The Role of Vortex Strings in the Non-Compact Lattice Abelian Higgs Model
Michael Chavel
The non-compact lattice version of the Abelian Higgs model is studied in terms of its topological excitations. The Villain form of the partition function is represented as a sum ov…
