Hamilton Principle for Chiral Anomalies in Hydrodynamics
P. B. Wiegmann
We developed the spacetime-covariant Hamilton principle for barotropic flows of a perfect fluid in the external axial-vector potential conjugate to the helicity current. Such flows…
Anomalies in fluid dynamics: flows in a chiral background via variational principle
Alexander G. Abanov, Paul B. Wiegmann
We study flows of barotropic perfect fluid under the simultaneous action of the electromagnetic field and the axial-vector potential, the external field conjugate to the fluid heli…
Chiral Anomaly in Euler Fluid and Beltrami Flow
P. B. Wiegmann, A. G. Abanov
We show that the chiral anomaly of quantum field theories with Dirac fermions subject to an axial background field is an inherent property of kinematics of a perfect classical flui…
Axial-Current Anomaly in Euler Fluid
A. G. Abanov, P. B. Wiegmann
We argue that a close analog of the axial-current anomaly of quantum field theories with fermions occurs in the classical Euler fluid. The conservation of the axial current (closel…
Quantum Hall effect and Quillen metric
Semyon Klevtsov, Xiaonan Ma, George Marinescu +1
We study the generating functional, the adiabatic curvature and the adiabatic phase for the integer quantum Hall effect (QHE) on a compact Riemann surface. For the generating funct…
On harmonic measure of critical curves
E. Bettelheim, I. Rushkin, I. A. Gruzberg +1
Fractal geometry of critical curves appearing in 2D critical systems is characterized by their harmonic measure. For systems described by conformal field theories with central char…
