Pseudospin and spin symmetries in the relativistic harmonic oscillator
(2006-12-01)
We compute the analytical solutions of the generalized relativistic harmonic oscillator in 1+1 dimensions, including a linear pseudoscalar potential and quadratic scalar and vector potentials which have equal or opposite ...

Lyra scalar-tensor theory: A scalar-tensor theory of gravity on Lyra manifold
(2021-06-15)
We present a scalar-tensor theory of gravity on a torsion-free and metric compatible Lyra manifold. This is obtained by generalizing the concept of physical reference frame by considering a scale function defined over the ...
Can dark matter be a scalar field?
(Iop Publishing Ltd, 2016-08-01)
In this paper we study a real scalar field as a possible candidate to explain the dark matter in the universe. In the context of a free scalar field with quadratic potential, we have used Union 2.1 SN Ia observational data ...
A Note on Scalar Field Theory in AdS3/CFT2
(World Scientific, 2010-06)
We consider a scalar field theory in AdSd+1, and introduce a formalism on surfaces at equal values of the radial coordinate. In particular, we define the corresponding conjugate momentum. We compute the Noether currents ...

Scalar and vector massive fields in Lyra’s manifold
(2004-01-01)
The problem of coupling between spin and torsion is analysed from a Lyra’s manifold background for scalar and vector massive fields using the Duffin-Kemmer-Petiau (DKP) theory. We found the propagation of the torsion is ...
