ABSTRACT: We review some recent results about the exploration of strong interactions in presence of external background fields by means of lattice QCD simulations. We discuss in particular studies concerning the influence of the external fields on the nonperturbative properties of the QCD vacuum and of the QCD phase diagram.Journal of Physics Conference Series 04/2013; 432(1):2004.

ABSTRACT: The properties of twoflavored massive NambuJonaLasinio model in (1+1)dimensional spacetime are investigated in the presence of isospin and quark number chemical potentials. The consideration is performed in the large$N_c$ limit, where $N_c$ is the number of colored quarks. It is shown in the framework of this model that charged pion condensation phenomenon of dense quark/hadron isotopically asymmetric matter is rather a spatially inhomogeneous than a homogeneous one.Physical review D: Particles and fields 06/2012; 86(8).

ABSTRACT: The zeta function regularization technique is used to study the finite temperature Casimir effect for a charged and massless scalar field confined between parallel plates and satisfying Dirichlet boundary conditions at the plates. A magnetic field perpendicular to the plates is included. Three equivalent expressions for the zeta function are obtained, which are exact to all orders in the magnetic field strength, temperature and plate distance. These expressions of the zeta function are used to calculate the Helmholtz free energy of the scalar field and the pressure on the plates, in the case of high temperature, small plate distance and strong magnetic field. In all cases, simple analytic expressions are obtained for the free energy and pressure which are accurate and valid for practically all values of temperature, plate distance and magnetic field.Physical Review D 04/2013; 88(10). · 4.69 Impact Factor
