Holographic anomalous chiral current near a boundary

Holographic anomalous chiral current near a boundary

Blog Article

Due to the Weyl anomaly, an axial vector field produces novel anomalous chiral currents in spacetime with boundaries.Remarkably, the chiral current is not invariant under the gauge transformation of axial vector fields.As a result, more potential 20wm01snus terms appear, and the chiral current becomes larger than the electric current near the boundary.

This paper investigates the anomalous chiral current in AdS/BCFT.We find that the minimal holographic model of the axial vector field cannot produce the expected chiral k2 raygun 2023 current.To resolve this problem, we propose adding a suitable boundary action.

Furthermore, we notice a similar situation for holographic condensation.Finally, we obtain the shape dependence of holographic chiral current and verify that it agrees with the field-theoretical result.
