The Noncommutative Harmonic Oscillator based in Simplectic Representation of Galilei Group
R. G. G. Amorim, S. C. Ulhoa, A. E. Santana
In this work we study symplectic unitary representations for the Galilei group. As a consequence the Schrödinger equation is derived in phase space. The formalism is based on the n…
Gravitational waves and the breaking of parallelograms in space-time
J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto
We show that plane-fronted gravitational waves induce the breaking of parallelograms in space-time, in the context of the teleparallel equivalent of general relativity (TEGR). The…
On Non-commutative Corrections of Gravitational Energy in Teleparallel Gravity
S. C. Ulhoa, R. G. G. Amorim
In this work we use the theory of Teleparallelism Equivalent to General Relativity based in non-commutative space-time coordinates. In this context, we write the corrections of the…
Neutron Stars in Teleparallel Gravity
S. C. Ulhoa, P. M. M. Rocha
In this paper we deal with neutron stars, which are described by a perfect fluid model, in the context of the teleparallel equivalent of general relativity. We use numerical simula…
