Analog Model for Euclidean Wormholes Effects
G. O. Heymans, N. F. Svaiter, G. Krein
Using results of statistical field theory for systems with an anisotropic disorder, we present an analog model for Euclidean wormholes and topological fluctuation effects in a Riem…
Restoration of a Spontaneously Broken Symmetry in an Euclidean Quantum model with Quenched Disorder
G. O. Heymans, N. F. Svaiter, G. Krein
We investigate the low temperature behavior of a system in a spontaneously broken symmetry phase described by an Euclidean quantum model with quenched disorder. Usin…
Quantum phase transitions in a bidimensional scalar field model
Gustavo O. Heymans, Marcus Benghi Pinto, Rudnei O. Ramos
We analyze the possible quantum phase transition patterns occurring within the scalar multi-field model at vanishing temperatures in -dimensions…
Critical behavior of the 2d scalar theory: resumming the perturbative mass gap
Gustavo O. Heymans, Marcus Benghi Pinto
We apply the optimized perturbation theory (OPT) to resum the perturbative series describing the mass gap of the bidimensional theory in the symmetric phase. A…
