The development of quantum theory on a torus has a long history, and can be traced back to
the 1920s, with the attempts by Nordström, Kaluza and Klein to define a fourth spatial …

The analytical expressions for both diagonal and off-diagonal ac and dc conductivities of
graphene placed in an external magnetic field are derived. These conductivities exhibit …

We investigate finite-size effects on the phase structure of chiral and difermion condensates
at finite temperature and density in the framework of the two-dimensional large-N Nambu …

The properties of the two-flavored Gross-Neveu model in the (1+ 1)-dimensional R 1× S 1
spacetime with compactified space coordinate are investigated in the presence of the …

We study the size dependence of the dynamical symmetry breaking in the four-dimensional
Nambu–Jona-Lasinio model. We show that the presence of boundaries reduces the chiral …

We investigate finite-size effects on the chiral transition at finite temperature and density in
the framework of the Nambu-Jona-Lasinio model in the presence of an external magnetic …

This paper presents a study of the free energy and particle density of the relativistic Landau
problem, and their relevance to the quantum Hall effect. First we study the zero-temperature …

We investigate finite-size effects on the phase structure of difermion condensates at finite
temperature and density in the framework of the two-dimensional large-N limit Nambu–Jona …

We study the zero temperature Casimir energy and fermion number for Dirac fields in a (2+
1)-dimensional Minkowski space-time, in the presence of a uniform magnetic field …

In this paper, a complete description of the zeta functions and corresponding zeta
determinants for Dirac and Laplace-type operators over finite cylinders using the contour …
