Energy levels for -symmetric deformation of the Mathieu equation
E. Cavalcanti, N. M. Alvarenga, F. Reis +3
We propose a non-Hermitian deformation of the Mathieu equation that preserves symmetry and study its spectrum and the transition from -unbroken to $\ma…
The effect of boundary conditions on dimensionally reduced field-theoretical models at finite temperature
E. Cavalcanti, C. A. Linhares, J. A. Lourenço +1
Here we understand \textit{dimensional reduction} as a procedure to obtain an effective model in dimensions that is related to the original model in dimensions. To explor…
Finite-volume and magnetic effects on the phase structure of the three-flavor Nambu--Jona-Lasinio model
L. M. Abreu, E. B. S. Corrêa, C. A. Linhares +1
In this work we analyze the finite-volume and magnetic effects on the phase structure of a generalized version of Nambu--Jona-Lasinio model with three quark flavors. By making use…
Dimensional reduction of a finite-size scalar field model at finite temperature
E. Cavalcanti, J. A. Lourenço, C. A. Linhares +1
We investigate the process of dimensional reduction of one spatial dimension in a thermal scalar field model defined in dimensions (inverse temperature and spatial dimens…
Appearance and disappearance of thermal renormalons
Erich Cavalcanti, José A Lourenço, Cesar A Linhares +1
We consider a scalar field model with a interaction and compute the mass correction at next-to-leading order in a large- expansion to study the summability of the pert…
Properties of size-dependent models having quasiperiodic boundary conditions
E. Cavalcanti, C. A. Linhares, A. P. C. Malbouisson
Boundary conditions effects are explored for size-dependent models in thermal equilibrium. Scalar and fermionic models are used for (films), (hollow cylinder) and $…
