Higher derivative Hořava-Lifshitz fermions: from superconductivity to atomic spectroscopy
A. A. Araújo Filho, K. E. L. de Farias, N. Heidari +2
We investigate an isotropic Hořava-Lifshitz fermion theory supplemented by a dimension-six spatial derivative operator, preserving first order time evolution while modifying the ul…
Newtonian Potential in Weyl Gravitoelectromagnetism
L. A. S. Evangelista, A. F. Santos
The gauge structure of the Weyl Gravitoelectromagnetic (GEM) formalism has been investigated, showing that although the theory admits additional propagating modes, only an effectiv…
Casimir phenomena in bumblebee gravity
D. S. Cabral, A. A. Araújo Filho, A. F. Santos
In this work, we analyze the Casimir effect associated with a massive, non-minimally coupled scalar field in static, spherically symmetric black hole spacetimes arising in bumblebe…
Gravitational Lorentz-violating scattering
L. A. S. Evangelista, A. F. Santos
We investigate the gravitational scattering process within the framework of gravitoelectromagnetism, a weak-field approximation of gravity analogous to Ma…
Gravitational Compton scattering at zero and finite temperature
L. A. S. Evangelista, A. F. Santos
The Lagrangian formulation of Gravitoelectromagnetism (GEM) theory is considered. GEM is a gravitational theory constructed based on the similarities between gravity and electromag…
