Possible higher order correction to the chiral vortical conductivity in a gauge field plasma

The two-loop contributions to the chiral vortical conductivity are considered. The Kubo formula together with the anomalous Ward identity of the axial vector current suggest that there may be a nonzero correction to the coefficient of the

Magnetic and inverse magnetic catalysis in the Bose-Einstein condensation of neutral bound pairs

In this paper, we shall address some field theoretic issues regarding the chiral magnetic effect. The general structure of the chiral magnetic current consistent with the electromagnetic gauge invariance is obtained and the impact of the infrared divergence is examined. Some subtleties on the relation between the chiral magnetic effect and the axial anomaly are clarified through a careful examination of the infrared limit of the relevant thermal diagrams.

Momentum Analyticity of Transverse Polarization Tensor in the Normal Phase of a Holographic Superconductor

super symmetric Yang-Mills theory is carried out to the sub-leading term in the large ’t Hooft coupling λ at a nonzero temperature. The strong coupling corresponds to the semi-classical expansion of the string-sigma model, the gravity dual of the Wilson loop operator, with the sub-leading term expressed in terms of functional determinants of fluctuations. The contribution of these determinants are evaluated numerically. We find the jet quenching parameter is reduced due to world sheet fluctuations by a factor (1 − 1.97λ−1/2).

The momentum analyticity of two point correlators from perturbation theory and AdS/CFT

The Bose-Einstein condensation of bound pairs made of oppositely charged fermions in a magnetic field is investigated. We find that the condensation temperature shows the magnetic catalysis effect in weak coupling and the inverse magnetic catalysis effect in strong coupling. The different responses to the magnetic field can be attributed to the competition between the dimensional reduction by Landau orbitals in pairing dynamics and the anisotropy of the kinetic spectrum of fluctuations (bound pairs in the normal phase)
