Description
Recently discovered Dirac Semimetals Na3Bi and Cd3As2 provide
perfect opportunity for investigation of phenomena which
were usually attibuted to high energy physics. The reason for this
is the existence of two massless Dirac fermions in the quasi-particle
dispersion relation for these materials.
One of the manifestations of the chiral anomaly, Chiral Magnetic Effect,
can be be observed in these materials as a large magnetoconductivity.
We study the conductivity of these materials in external magnetic field
within lattice effective field theory approach.
Our results confirm the existence of Chiral Magnetic Effect in Dirac Semimetals.
