(Elsevier, 2020)A new approach to find exact solutions to one-dimensional quantum mechanical systems is devised. The scheme is based on the introduction of a potential function for the wavefunction, and the equation it satisfies. We recover ...
-
(American Physical Society, 2017)Exact electromagnetic wave solutions to Maxwell equations on anisotropic Bianchi I cosmological spacetime backgrounds are studied. The waves evolving on Bianchi I spacetimes exhibit birefringence (associated with linear ...
-
(IOP Publishing, 2013)The Lagrangian equations of motion for massive spinning test particles (tops) moving on a gravitational background using general relativity are presented. The paths followed by tops are nongeodesic.An exact solution for ...

Casimir force induced by electromagnetic wave polarization in Kerr, Gödel and Bianchi–i spacetimes (Springer, 2020)Electromagnetic waves propagation on either rotating or anisotropic spacetime backgrounds (such as Kerr and Godel metrics, or Bianchi-I metric) produce a reduction of the magnitude of Casimir forces between plates. These ...

(2009)The dispersion relation for circularly polarized electromagnetic waves propagating in the direction of an external magnetic field in a relativistic electron-positron plasma with arbitrary constant drift velocities is ...

Class of Exact Solutions for a Cosmological Model of Unified Gravitational and Quintessence Fields (Springer, 2017)A new approach to tackle Einstein equations for an isotropic and homogeneous Friedmann-Robertson-Walker Universe in the presence of a quintessence scalar field is devised. It provides a way to get a simple exact solution ...
-
(IOP, 2020)It is showed that, in general, classical and quantum dispersion relations are different due to the presence of the Bohm potential. There are exact particular solutions of the quantum (wave) theory which obey the classical ...
-
(Optical Society of America, 2017)In the last ten years, the technology of differential geometry, ubiquitous in gravitational physics, has found its place in the field of optics. It has been successfully used in the design of optical metamaterials through ...
-
(IOP Publishing Ltd, 2017)We find exact solutions to Maxwell equations written in terms of fourvector potentials in non-rotating, as well as in Gdel and Kerr spacetimes. We show that Maxwell equations can be reduced to two uncoupled secondorder ...
-
(Elsevier, 2020)It is shown that the Schrodinger equation for a large family of pairs of two-dimensional quantum potentials possess wavefunctions for which the amplitude and the phase are interchangeable, producing two different solutions ...
-
(American Physical Society, 2020)The existence of nonvanishing Bohm potentials, in the Madelung-Bohm version of the Schrodinger equation, allows for the construction of particular solutions for states of quantum particles interacting with nontrivial ...
-
(IOP Publishing, 2017-06-08)Recent experimental work has determined that free falling Rb-87 atoms on Earth, with vertically aligned spins, follow geodesics, thus apparently ruling out spin-gravitation interactions. It is showed that while some spinning ...
