The Chern-Simons Diffusion Rate in Improved Holographic QCD
Umut Gursoy, Ioannis Iatrakis, Elias Kiritsis +2
In (3+1)-dimensional SU(Nc) Yang-Mills (YM) theory, the Chern-Simons diffusion rate, Gamma_{CS}, is determined by the zero-momentum, zero-frequency limit of the retarded two-point…
Holographic models for undoped Weyl semimetals
Umut Gursoy, Vivian Jacobs, Erik Plauschinn +2
We continue our recently proposed holographic description of single-particle correlation functions for four-dimensional chiral fermions with Lifshitz scaling at zero chemical poten…
On the Temperature Dependence of the Shear Viscosity and Holography
Sera Cremonini, Umut Gursoy, Phillip Szepietowski
We examine the structure of the shear viscosity to entropy density ratio eta/s in holographic theories of gravity coupled to a scalar field, in the presence of higher derivative co…
