Hyperscaling Violation

We investigated quasinormal frequencies (QNFs) in black brane with hyperscaling violating by using the continued fractions method. We calculate QNF of massless scalar field and electromagnetic field both with zero spatial momentum, find that QNFs have negative imaginary frequency suggesting black brane with hyperscaling violation is stable under those perturbations.

Hyperscaling Violation

In this paper we consider a metric with hyperscaling violation on a black brane background. In this background we calculate the ratio of shear viscosity to entropy density with hydrodynamics information. The calculation of this quantity leads us to a constraint on θ as 3 ≤ θ < 4, and θ ≤ 0. In that case we show that the quantity η/s is not dependent on hyperscaling violation parameter θ. Our results about ratio of shear viscosity to entropy density from the QCD point of view agree with other works in the literature as 1/4π.
