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…
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 $…
Quantum field theory on toroidal topology: algebraic structure and applications
F. C. Khanna, A. P. C. Malbouisson, J. M. C. Malbouisson +1
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 di…
Spontaneous symmetry restoration in a field theory at finite chemical potential in a toroidal topology
C. A. Linhares, A. P. C. Malbouisson, J. M. C. Malbouisson +1
We consider the massive vector -component theory defined on a Euclidean space with a toroidal topology. Using recently developed methods to perform a compactifica…
