Non-hermitian phase transitions on a generalized Ellis-Bronnikov wormhole bridge
José A. S. Lourenço, Ygor Pará, J. Furtado
In this paper, we investigate the emergence of non-Hermitian phase transitions on a quantum wormhole surface. We consider a single fermion whose dynamics are governed by the Dirac…
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 bosonic and fermionic propagators under an external electromagnetic field in a Euclidean manifold
Emerson B. S. Corrêa, Carlos André Bahia, José André Lourenço
In this paper, we will calculate the bosonic as well as fermionic propagators under classical homogeneous and constant magnetic and electric fields in a Euclidean space. For this,…
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…
