Spectrum of anomalous magnetohydrodynamics

  title={Spectrum of anomalous magnetohydrodynamics},
  author={Massimo Giovannini},
  journal={Physical Review D},
The equations of anomalous magnetohydrodynamics describe an Abelian plasma where conduction and chiral currents are simultaneously present and constrained by the second law of thermodynamics. At high frequencies the magnetic currents play the leading role and the spectrum is dominated by two-fluid effects. The system behaves instead as a single fluid in the low-frequency regime where the vortical currents induce potentially large hypermagnetic fields. After deriving the physical solutions of… 
The generation of matter–antimatter asymmetries and hypermagnetic fields by the chiral vortical effect of transient fluctuations
We study the contribution of temperature-dependent chiral vortical effect to the generation and evolution of the hypermagnetic fields and the matter-antimatter asymmetries, in the symmetric phase of
Hypermagnetic knots and gravitational radiation at intermediate frequencies
The maximally gyrotropic configurations of the hypermagnetic field at the electroweak epoch can induce a stochastic background of relic gravitational waves with comoving frequencies ranging from the
Evolution of the baryon asymmetry through the electroweak crossover in the presence of a helical magnetic field
We elaborate upon the model of baryogenesis from decaying magnetic helicity by focusing on the evolution of the baryon number and magnetic field through the Standard Model electroweak crossover. The

Effects of nonhelical component of hypermagnetic field on the evolution of the matter-antimatter asymmetry, vorticity, and hypermagnetic field
We study the evolution of the matter-antimatter asymmetry (η), the vorticity, and the hypermagnetic field in the symmetric phase of the early Universe, and in the temperature range 100 GeV ≤ T ≤ 10
Contribution of the chiral vortical effect to the evolution of the hypermagnetic field and the matter-antimatter asymmetry in the early Universe
In this paper, we study the contribution of the chiral vortical effect, in addition to that of the chiral magnetic effect, to the evolution of the hypermagnetic field and the matter-antimatter


Chiral Alfvén Wave in Anomalous Hydrodynamics.
A new type of gapless collective excitation induced by chiral effects in an external magnetic field is found, a transverse wave, present even in incompressible fluids, unlike the chiral magnetic and chiral vortical waves.

On chiral magnetic effect and holography
We point out that there is a difference between the behavior of fermionic systems (and their holographic analogs) in a background axial vector field, on the one hand, and at finite chiral chemical
