DESCRIPTION:Title: \;Chiral magnetic transport from holography &\; h
ydrodynamics\n\nAbstract: \;After a brief review of hydrodynamics and
holography\, we compute quasinormal modes (QNMs) of the metric and gauge f
ield perturbations about black branes electrically and magnetically charge
d in the Einstein-Maxwell-Chern-Simons theory. By the gauge/gravity corres
pondence\, this theory is dual to a particular class of field theories wit
h a chiral anomaly\, in a thermal charged plasma state subjected to a cons
tant external magnetic field\, B. The QNMs are dual to the poles of the tw
o-point functions of the energy-momentum and axial current operators\, and
they encode information about the dissipation and transport of charges in
the plasma. Complementary to the gravity calculation\, we work out the hy
drodynamic description of the dual field theory in the presence of a chira
l anomaly\, and a constant external B. We find good agreement with the wea
k field hydrodynamics\, which can extend beyond the weak B regime into int
ermediate regimes. Furthermore\, we provide results that can be tested aga
inst thermodynamics and hydrodynamics in the strong B regime. We find QNMs
exhibiting Landau level behavior\, which become long-lived at large B if
the anomaly coefficient exceeds a critical magnitude. Chiral transport is
analyzed beyond the hydrodynamic approximation for the five (formerly) hyd
rodynamic modes\, including a chiral magnetic wave.\nHEP Jun6 flyer

\n**Abstract:** \;After a brief review of hydrodynamics and holography\, we compu
te quasinormal modes (QNMs) of the metric and gauge field perturbations ab
out black branes electrically and magnetically charged in the Einstein-Max
well-Chern-Simons theory. By the gauge/gravity correspondence\, this theor
y is dual to a particular class of field theories with a chiral anomaly\,
in a thermal charged plasma state subjected to a constant external magneti
c field\, B. The QNMs are dual to the poles of the two-point functions of
the energy-momentum and axial current operators\, and they encode informat
ion about the dissipation and transport of charges in the plasma. Compleme
ntary to the gravity calculation\, we work out the hydrodynamic descriptio
n of the dual field theory in the presence of a chiral anomaly\, and a con
stant external B. We find good agreement with the weak field hydrodynamics
\, which can extend beyond the weak B regime into intermediate regimes. Fu
rthermore\, we provide results that can be tested against thermodynamics a
nd hydrodynamics in the strong B regime. We find QNMs exhibiting Landau le
vel behavior\, which become long-lived at large B if the anomaly coefficie
nt exceeds a critical magnitude. Chiral transport is analyzed beyond the h
ydrodynamic approximation for the five (formerly) hydrodynamic modes\, inc
luding a chiral magnetic wave.
