Universal relations of transport coefficients from holography
Aleksey Cherman, Abhinav Nellore
We show that there are universal high-temperature relations for transport coefficients of plasmas described by a wide class of field theories with gravity duals. These theories can…
A bound on the speed of sound from holography
Aleksey Cherman, Thomas D. Cohen, Abhinav Nellore
We show that the squared speed of sound v_{s}^{2} is bounded from above at high temperatures by the conformal value of 1/3 in a class of strongly coupled four-dimensional field the…
A sticky business: the status of the conjectured viscosity/entropy density bound
Aleksey Cherman, Thomas D. Cohen, Paul M. Hohler
There have been a number of forms of a conjecture that there is a universal lower bound on the ratio, eta/s, of the shear viscosity, eta, to entropy density, s, with several differ…
A tale of two skyrmions: the nucleon's strange quark content in different large N_c limits
Aleksey Cherman, Thomas D. Cohen
The nucleon's strange quark content comes from closed quark loops, and hence should vanish at leading order in the traditional large (TLNC) limit. Quark loops are not suppres…
