Exact group invariant scar towers in two dimensional gauge theories
João Barata, Kiryl Pakrouski, Andrey V. Sadofyev
We construct exact many-body scar towers in two dimensional gauge theories with two flavors of massless fundamental fermions. For oppositely charged fermions, the scar subspace is…
Chiral Vortical Instability
Shuai Wang, Koichi Hattori, Xu-Guang Huang +1
We revisit the collective modes of chiral matter described by the second-order chiral hydrodynamics, noticing that chiral shear waves (CSWs) may become unstable for momenta above a…
Axions and Superfluidity in Weyl Semimetals
Emil Mottola, Andrey V. Sadofyev, Andreas Stergiou
An effective field theory (EFT) for dynamical axions in Weyl semimetals (WSMs) is presented. A pseudoscalar axion excitation is predicted in WSMs at sufficiently low temperatures,…
Zilch Vortical Effect, Berry Phase, and Kinetic Theory
Xu-Guang Huang, Pavel Mitkin, Andrey V. Sadofyev +1
Rotating photon gas exhibits a chirality separation along the angular velocity which is manifested through a generation of helicity and zilch currents. In this paper we study this…
Drag force to all orders in gradients
Jared Reiten, Andrey V. Sadofyev
We study the energy loss of a heavy quark slowly moving through an evolving strongly coupled plasma. We use the linearized fluid/gravity correspondence to describe small perturbati…
Chiral Waves on the Fermi-Dirac Sea: Quantum Superfluidity and the Axial Anomaly
Emil Mottola, Andrey V. Sadofyev
We show that as a result of the axial anomaly, massless fermions at zero temperature define a relativistic quantum superfluid. The anomaly pole implies the existence of a gapless C…
