The University

A finite ultraviolet cutoff near a reflecting boundary yields a stress tensor that violates the basic energy-pressure relation. Therefore, a "soft" wall described by a power-law potential, which needs no ad hoc cutoff, is being investigated by the collaboration centered at Texas A&M University and the University of Oklahoma. Progress is reported here.

Hyperscaling Violation

In this paper we use a metric with hyperscaling violation and study form factor of QCD. We find the effects of hyperscaling violation on the form factor and obtain the dependence of the form factor on momentum numerically. Here by using the hyperscaling violation metric we do not need hard-wall and soft-wall models.

Finite Temperature Qcd

We review 5D holographic approaches to finite temperature QCD. Thermodynamic properties of the "hard-wall" and the "soft-wall" models are derived. Various non-realistic features in these models are rectified by the setup of improved holographic QCD, that we review here.
