LyST: a Scalar-Tensor Theory of Gravity on Lyra Manifold
R. R. Cuzinatto, E. M. de Morais, B. M. Pimentel
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 cons…
Bopp-Podolsky black holes and the no-hair theorem
R. R. Cuzinatto, C. A. M. de Melo, L. G. Medeiros +2
Bopp-Podolsky electrodynamics is generalized to curved space-times. The equations of motion are written for the case of static spherically symmetric black holes and their exterior…
Electromagnetic Field in Lyra Manifold: A First Order Approach
R. Casana, C. A. M. de Melo, B. M. Pimentel
We discuss the coupling of the electromagnetic field with a curved and torsioned Lyra manifold using the Duffin-Kemmer-Petiau theory. We will show how to obtain the equations of mo…
Schwarzschild and de Sitter solutions from the argument by Lenz and Sommerfeld
R. R. Cuzinatto, B. M. Pimentel, P. J. Pompeia
The Lenz-Sommerfeld argument allows an ingenious and simple derivation of the Schwarzschild solution of Einstein equations of general relativity. In this paper, we use the same rea…
Spinorial Field and Lyra Geometry
R. Casana, C. A. M. de Melo, B. M. Pimentel
The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation…
Massless DKP field in Lyra manifold
R. Casana, C. A. M. de Melo, B. M. Pimentel
Massless scalar and vector fields are coupled to Lyra geometry by means of Duffin-Kemmer-Petiau (DKP) theory. Using Schwinger Variational Principle, equations of motion, conservati…
