Nuclear Physics Seminar
"Transport Functions from Fluid/Gravity Correspondence"
Presented by Michael Lublinsky, Ben-Gurion University
Friday, July 22, 2016, 2:00 pm — Small Seminar Room, Bldg. 510
Transport coefficients in two systems are addressed via holographic methods originating from the AdS/CFT.
The first system is a neutral conformal fluid. In linearised hydrodynamics, beyond shear viscosity, all order gradient
expansion can be efficiently resummed into two momenta-dependent transport coefficient functions. The second system is an e/m current coupled via chiral anomaly to an axial U(1) current. The anomaly-free all order transport coefficients are resummed into three momenta-dependent functions, the diffusion function and two conductivities. Anomaly-induced transport, resummed to all orders, generalises the chiral-magnetic effect (CME) and related phenomena. Novel, anomaly-induced non-linear effects will be presented too.
