LIV effects on the quantum stochastic motion in an acoustic FRW-geometry
M. A. Anacleto, C. H. G. Bessa, F. A. Brito +3
It is well known in the literature that vacuum fluctuations can induce a random motion of particles which is sometimes called quantum Brownian motion or quantum stochastic motion.…
Cosmology from an exponential dependence on the trace of the energy-momentum tensor -- Numerical approach and cosmological tests
G. Ribeiro, R. Sfair, P. H. R. S. Moraes +2
In this paper, we present the cosmological scenario obtained from gravity by using an exponential dependence on the trace of the energy-momentum tensor. With a numerical a…
Cosmology from a running vacuum model driven by a scalar field
J. R. L. Santos, P. H. R. S. Moraes
The possibility that the vacuum energy density is, indeed, varying in time, has been investigated lately from the running vacuum models perspective. Motivated by such models,…
Building analytical three-field cosmological models
J. R. L. Santos, P. H. R. S. Moraes, D. A. Ferreira +1
A difficult task to deal with is the analytical treatment of models composed by three real scalar fields, once their equations of motion are in general coupled and hard to be integ…
