摘要：We obtain axionic charged primordial black holes on a vacuum created gravitational pair of(33)-braneby the Kalb-Ramond field on a D4-brane in presence of a background open string metric.The new geometries on anemergent pair of (33)-brane universe is shown to be influenced by the non -perturbative quantum effects underlying ageometric torsion in a second order formalism. The presence of small extra dimensions transverse to the pair in theformalism ensures dynamical scalarfields hidden to a 3brane or a3-brane universe. We investigate the non-perturbativequantum vacua for their characteristic properties to explain the accelerated expansion of our universe. Interestingly theemergent brane universe is shown to possess its origin in degenerate stringy de Sitter vacuaat an early epoch. A nonperturbativeD brane world volume correction for p > 3 is worked outto explain some of the quantum effectsunderlying aquintessence axion in the string-brane setup.Our analysis reveals that a D-instanton can be a potentialcandidate to source the dark energy inour brane universe.
