Violation of universal lower bound for the shear viscosity to entropy density ratio in dark energy dominated accretion
Abstract The universal lower bound of the ratio of shear viscosity to entropy density is suggested by the string theory and gauge duality for any matter. We examined the ratio of shear viscosity to entropy density for viscous accretion flow towards a central gravitating object in the presence of dar...
