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…
