Charged Randall-Sundrum Braneworld Type II with Higher Order Curvature Corrections from Superstring Arguments and Dominated by Quintessence

摘要

We discuss a new class of RSH braneworld cosmology exhibiting accelerated expansion and dominated byquintessence. It is explicitly demonstrated that the universe expansion history (transition from inflation to decelerationepoch to acceleration and effective quintessence era) may naturally occur in such unified theory for some classes of inversescalar potentials. Besides a decaying effective cosmological constant, the model incorporates an increasing black holemass, an increasing Maxwellian electrical charge with cosmic time and a time-dependent brane tension. The cosmologicalmodel exhibits several features of cosmological and astrophysical interest for both the early and late universe consistentwith recent observations, in particular the ones concerned with the gravitational constants, black holes masses andcharges and variation of the gauge coupling parameters with cosmic time. One interesting mark of the constructedmodel concerns the fact that a black hole mass surrounded by quintessence energy may increase with time even if thehorizon disappears.
