-function for a model with spectral dependent boundary conditions
H. Falomir, M. Loewe, E. Muñoz +1
We explore the meromorphic structure of the -function associated to the boundary eigenvalue problem of a modified Sturm-Liouville operator subject to spectral dependent boundary…
Considerations about Gribov ambiguities for the abelian Higgs model in the presence of chemical potential and temperature
R. Benguria, M. Loewe, R. A. Santos
In this letter we discuss the influence of a U(1) chemical potential on the existence of Gribov copies in a U(1) theory at finite temperature . We show that the chemical pot…
Isospin Chemical potential and temperature effects in the Linear Sigma Model
M. L. El-Sheikh, M. Loewe
In this letter we explore the temperature and isospin chemical potential () dependence of the vacuum structure and the meson masses in the linear sigma model, at the one loop…
Hadrons as Skyrmions in the presence of isospin chemical potential
M. Loewe, S. Mendizabal, J. C. Rojas
The stability of the Skyrmion solution in the presence of finite isospin chemical potential is considered, showing the existence of a critical value MeV where t…
Skyrmions, Hadrons and isospin chemical potential
M. Loewe, S. Mendizabal, J. C. Rojas
Using the Hamiltonian formulation, in terms of collective variables, we explore the evolution of different skyrmionic parameters as function of the isospin chemical potential ()…
Background field method at finite temperature and density
M. Loewe, S. Mendizabal, J. C. Rojas
In this letter we make use of the Background Field Method (BFM) to compute the effective potential of an SU(2) gauge field theory, in the presence of chemical potential and tempera…
