1305.0340 (Sayantani Bhattacharyya et al.)

Second order transport from anomalies    [PDF]

Sayantani Bhattacharyya, Justin R. David, Somyadip Thakur
We study parity odd transport at second order in derivative expansion for a non-conformal charged fluid. We see that there are 29 parity odd transport coefficients, of which 12 are non-vanishing in equilibrium. We use the equilibrium partition function method to express 7 of these in terms of the anomaly, shear viscosity, charge diffusivity and thermodynamic functions. The remaining 5 are constrained by 3 relations which also involve the anomaly. We derive Kubo formulae for 2 of the transport coefficients and show these agree with that derived from the equilibrium partition function.
