Exploring the shear viscosity in four-dimensional planar black holes beyond general relativity

M Bravo-Gaete, L Guajardo, FF Santos - Physical Review D, 2023 - APS
The well-known shear viscosity to entropy density ratio (η/s) cannot be computed when the
black hole space-time has zero thermodynamic entropy. This is the case, for example, when …
