Galactic core-tail structure in BEC dark matter with Kapitza potential
Itauany do Nascimento Barroso, Hermano Velten
Recently, the experimental realization of a Kapitza potential in a Bose-Einstein Condensate (BEC) has been reported for the first time in literature, motivating further theoretical…

Anisotropic quantum polytropes
Hermano Velten, Felipe S. Escórcio, Nadson J. S. Trindade
The structure of astrophysical objects is usually modeled under the assumption of hydrostatic equilibrium. However, actual configurations may deviate from perfect spherical or isot…

Cosmological eras with the neutrino non-relativistic transition in RTB gravity
Jonas Pinheiro da Silva, Hermano Velten
Theories based on the Ricci and the trace of the energy-momentum tensor, or the short name Ricci-trace-based (RTB) theories, represent a gravitational approach based on the Ricci s…
