Non-linear Plane Gravitational Waves as Space-time Defects
F. L. Carneiro, S. C. Ulhoa, J. W. Maluf +1
We consider non-linear plane gravitational waves as propagating space-time defects, and construct the Burgers vector of the waves. In the context of classical continuum systems, th…
A teleparallel type theory for massless spin 2 fields
J. W. Maluf, S. C. Ulhoa
We present the Lagrangian and Hamiltonian formulations of a theory for spin 2 fields. The construction is developed in flat space-time. The construction in curved space-time is con…
On Regular Black Holes at Finite Temperature
S. C. Ulhoa, E. P. Spaniol, R. Gomes +2
The Thermo Field Dynamics (TFD) formalism is used to investigate the regular black holes at finite temperature. Using the Teleparalelism Equivalent to General Relativity (TEGR) the…
Analytical Solution for Gross-Pitaevskii Equation in Phase Space and Wigner Function
A. X. Martins, R. A. S. Paiva, G. Petronilo +4
In this work we study symplectic unitary representations for the Galilei group. As a consequence a Non-Linear Schrödinger equation is derived in phase space. The formalism is based…
