Dirac Semimetals Na 3 Bi and Cd 3 As 2 are recently discovered materials, which low energy electronic spectrum is described by two flavours of massless 3+1D fermions. In order to study electronic properties of these materials we formulated lattice field theory with rooted staggered fermions on anisotropic lattice. It is shown that in the limit of zero temporal lattice spacing this theory reproduces effective theory of Dirac semimetals. Using the lattice field theory we study the phase diagramdoi:10.1051/epjconf/201817503001 fatcat:ysmpwzxuwrfcpbjwazvesvmab4
