Description
Despite abundant experimental evidence and numerical hydrodynamic simulations, transport of energy-momentum and charge in anisotropic plasma states, which are produced in off-central collisions, has not been adequately addressed from a theoretical point of view. In Ref. 1, a novel method was introduced, using holography to compute transport coefficients in strongly interacting plasma states in holographic QFTs. This method is based on relating the IR limit of fluctuations on a gravitational background to its variations providing a previously overlooked connection between boundary and near horizon data. The method was used to derive analytic formulas for the viscosities of an anisotropic plasma state in the presence of an external magnetic field or another isotropy breaking external source, as well as one further source of anisotropy. We now extended this method to include a further source of anisotropy, such as that produced by an axion, more closely mimicking realistic off-central heavy ion collisions.
