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…

Renormalons beyond the Borel plane
Erich Cavalcanti
The renormalon singularities are a known source of the divergent behavior of asymptotic perturbative series from field theoretical models. These singularities live in the Borel pla…

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…
