Dirac and Weyl semimetals are three-dimensional electronic systems with the Fermi level at or near a band crossing. Their low energy quasi-particles are described by a relativistic Dirac Hamiltonian with zero effective mass, challenging the standard Fermi liquid (FL) description of metals. In FL systems, electrical and thermo–electric transport coefficient are linked by very robust relations. The Mott relation links the thermoelectric and conductivity transport coefficients. In a previous…

Fingerprints of the conformal anomaly in the thermoelectric transport in Dirac and Weyl semimetals
In a recent work, a contribution to the Nernst current of a Dirac or Weyl semimetal coming from the conformal anomaly was reported. Being originated from an anomaly - a vacuum contribution -, a
Thermoelectric properties of Weyl and Dirac semimetals
We study the electronic contribution to the thermal conductivity and the thermopower of Weyl and Dirac semimetals using a semiclassical Boltzmann approach. We investigate the effect of various
Anomalous thermoelectric phenomena in lattice models of multi-Weyl semimetals
The thermoelectric transport coefficients are calculated in a generic lattice model of multi-Weyl semimetals with a broken time-reversal symmetry by using the Kubo's linear response theory. The
Thermoelectric Transport Coefficients for Massless Dirac Electrons in Quantum Limit
We perform an analytic calculation of thermoelectric transport coefficients for massless Dirac electrons using the approach based on the Kubo–Středa formula and generalized Mott's relation. The main
Anomalous transport of Weyl fermions in Weyl semimetals
We present a field theoretical model of anomalous transport in Weyl semimetals. We calculate the chiral magnetic and chiral vortical effect in the electric, axial (valley), and energy current. Our
Anomalous thermoelectric transport of Dirac particles in graphene.
The results underscore the anomalous thermoelectric transport in graphene, which may be used as a highly sensitive probe for impurity bands near the Dirac point.
Weyl and Dirac semimetals in three-dimensional solids
Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic excitations that are protected by topology and symmetry. As three-dimensional analogs of graphene, they have
Hydrodynamic theory of thermoelectric transport and negative magnetoresistance in Weyl semimetals
Negative thermal magnetoresistance is a sharp, experimentally accessible signature of this axial–gravitational anomaly, even beyond the hydrodynamic limit, in weakly disordered Weyl semimetals.
Berry-phase effect in anomalous thermoelectric transport.
A finite-temperature formula for the orbital magnetization is derived, which enables to provide an explicit expression for the off-diagonal thermoelectric conductivity, to establish the Mott relation between the anomalous Nernst and Hall effects, and to reaffirm the Onsager relations between reciprocal thermoelectedric conductivities.
Giant anomalous Nernst effect and quantum-critical scaling in a ferromagnetic semimetal
In conducting ferromagnets, an anomalous Nernst effect—the generation of an electric voltage perpendicular to both the magnetization and an applied temperature gradient—can be driven by the
