276. Generalised global symmetry and holography of dynamical extended objects

Nick Poovuttikul

10/5/17, 3:15 PM

I will discuss the concept of generalised global symmetry, which describe the conservation law associated to dynamical extended objects, and their implementation in holography. I will also discuss its application in the effective theory of matter in the presence of strong dynamical magnetic field as well as the incommensurate phase which breaks the translational symmetry spontaneously

277. Ward identities and relations between conductivities and viscosities in holography

David Rodríguez

10/5/17, 3:20 PM

We derive relations between viscosities and momentum conductivity in 2 + 1 dimensions by finding a generalization of holographic Ward identities for the energy-momentum tensor. The generalization is novel in the sense that it goes beyond the usual identities obtained from holographic renormalization. Our results are consistent with previous field theory analysis. The main tools we use...

278. Rindler Fluid with Weak Momentum Relaxation

Yun-Long Zhang

10/5/17, 3:25 PM

We realize the weak momentum relaxation in Rindler fluid, which lives on the time-like cutoff surface in an accelerating frame of flat spacetime. The translational invariance is broken by massless scalar fields with weak strength. Both of the Ward identity and the momentum relaxation rate of Rindler fluid are obtained, with higher order correction in terms of the strength of...
