We propose a way to introduce the currents responsible for the Chiral Magnetic Effect, and similar phenomena, into the AdS/CFT description. Such currents are thought to occur in heavy ion collisions due to topologically non-trivial field configurations and in dense stars due to beta decay. They may be responsible for the P and CP odd effects seen at RHIC and the anomalously large velocities observed in some pulsars. We discuss the boundary conditions that allow the phenomenon to exist in real… Expand
Chiral magnetic effect and holography
The chiral magnetic effect (CME) is a highly discussed effect in heavy-ion collisions stating that, in the presence of a magnetic field B, an electric current is generated in the background ofExpand
Topological Currents in Dense Matter
This thesis introduces the idea of a topological current that flows in regions with large magnetic fields, dense matter, and parity violation. We propose that such a current exists in the cores ofExpand

A chiral magnetic effect from AdS/CFT with flavor
For (3 + 1)-dimensional fermions, a net axial charge and externalmagneticfield can lead to a current parallel to the magnetic field. This is the chiral magnetic effect. We use gauge-gravity dualityExpand
The Chiral Magnetic Effect and anomaly-induced transport
The Chiral Magnetic Effect (CME) is the phenomenon of electric charge separation along the external magnetic field that is induced by the chirality imbalance. The CME is a macroscopic quantum effectExpand

TLDR
A three-particle azimuthal correlator is investigated which is a P even observable, but directly sensitive to the charge separation effect, and measurements of charged hadrons near center-of-mass rapidity with this observable are reported. Expand
