Extended Supersymmetric sigma-Model Based on the SO(2N+1) Lie Algebra of the Fermion Operators
Seiya Nishiyama, Joao da Providencia, Constanca Providencia +1
Extended supersymmetric sigma-model is given, standing on the SO(2N+1) Lie algebra of fermion operators composed of annihilation-creation operators and pair operators. Canonical tr…
A Refined Numerical Result on the First Excitation Energy in the Two-Level Pairing Model
Y. Tsue, C. Providencia, J. da Providencia +1
The first excitation energy in the two-level pairing model is investigated in terms of the equilibrium and the small fluctuation around it. The basic idea is an extension of result…
Dynamical chiral symmetry breaking by a magnetic field and multi-quark interactions
A. A. Osipov, B. Hiller, A. H. Blin +1
Catalysis of dynamical symmetry breaking by a constant magnetic field in (3+1) dimensions is considered. We use the three flavour Nambu -- Jona-Lasinio type model with 't Hooft and…
