Nonlinear chiral transport from holography

Understand

Nonlinear transport phenomena induced by the chiral anomaly are explored within a 4D field theory defined holographically as $U(1)_V\times U(1)_A$ Maxwell-Chern-Simons theory in Schwarzschild-$AdS_5$.

• First, in presence of external electromagnetic fields, a general form of vector and axial currents is derived.
• Then, within the gradient expansion up to third order, we analytically compute all (over 50) transport coefficients.
• A wealth of higher order (nonlinear) transport phenomena induced by chiral anomaly are found beyond the Chiral Magnetic and Chiral Separation Effects.
