Instantons and transseries of the Mathieu potential deformed by a -symmetry parameter
N. M. Alvarenga, E. Cavalcanti, C. A. Linhares +3
We investigate the non-perturbative effects of a deformation of the Mathieu differential equation consistent with symmetry. First, we develop a connection between th…

Influence of external magnetic field, finite-size effects and chemical potential on the phase transition of a complex scalar field
Erich Cavalcanti, Erick Castro, Cesar A. Linhares +1
A scalar model is built, as a quantum field theory defined on toroidal topologies, to describe phase transition in films subjected to periodic boundary conditions and influenced by…
