Viscous Dark Energy In Bianchi Type V Space-Time

General Physics 2017-12-13 v3

Abstract

We study the behavior of dark energy (DE) in the scope of anisotropic Bianchi type V (BV) space-time. First we derive Friedmann-Like Equations, then we compare the dark energy equation of state (EoS) parameter for viscous and non-viscous dark energy and make a correspondence between DE and quintessence and phantom descriptions of non-viscous and viscous dark energy and reconstruct the potential of these two scalar fields. The late time behavior of EoS parameter through a thermodynamical study has also been investigated. Finally, we investigate the conditions under which BV space-time can be mapped into the FRW and how the bulk viscose coefficient may affect dark energy EoS parameter of our ω\mboxBV\omega\mbox{BV} Model with constraints from 28 Hubble parameter, H(z)H(z), measurements at intermediate redshifts 0.07z2.30.07\leq z\leq 2.3.
