We study the resistivity of three-dimensional semimetals with linear dispersion in the presence of on-site electron-electron interaction. The well-known quadratic temperature dependence of the resistivity of conventional metals is turned into an unusual T^{6} behavior. An analogous change affects the thermal transport, preserving the linearity in T of the ratio between thermal and electrical conductivities. These results hold from weak coupling up to the nonperturbative region of the Mott…

Prototypical many-body signatures in transport properties of semiconductors

We devise a methodology for charge, heat, and entropy transport driven by carriers with finite lifetimes. Combining numerical simulations with analytical expressions for low temperatures, we

Topological semimetal driven by strong correlations and crystalline symmetry

Electron correlations amplify quantum fluctuations and, as such, are recognized as the origin of many quantum phases. However, whether strong correlations can lead to gapless topological states is an



Optical and transport properties in three-dimensional Dirac and Weyl semimetals

Within a Kubo formalism, we study dc transport and ac optical properties of 3D Dirac and Weyl semimetals. Emphasis is placed on the approach to charge neutrality and on the differences between Dirac

Kinks in the electronic specific heat.

It is found that the heat capacity of a strongly correlated metal presents striking changes with respect to Landau Fermi-liquid theory, implying that correlated materials are more resistive to cooling at low T than expected from the intermediate temperature behavior.

Generic susceptibilities of the half-filled Hubbard model in infinite dimensions

(Dated: April 3, 2009)Around a metal-to-insulator transition driven by repulsive interaction (Mott transition) the singleparticle excitations and the collective excitations are equally important.

High-Dimensional Disorder-Driven Phenomena in Weyl Semimetals, Semiconductors and Related Systems

It is commonly believed that a non-interacting disordered electronic system can undergo only the Anderson metal-insulator transition. It has been suggested, however, that a broad class of systems can

Screened moments and absence of ferromagnetism in FeAl

While the stoichiometric intermetallic compound FeAl is found to be paramagnetic in experiment, standard band-theory approaches predict the material to be ferromagnetic. We show that this discrepancy

Extremely high conductivity observed in the unconventional triple point fermion material MoP

Weyl and Dirac fermions have created much attention in condensed matter physics and material science. They are realized in semimetals that have 2-fold and 4-fold degenerate crossing points and

Topological nodal semimetals

We present a study of “nodal-semimetal” phases in which nondegenerate conduction and valence bands touch at points (the “Weyl semimetal”) or lines (the “line-node semimetal”) in three-dimensional

Thermoelectric properties of the degenerate hubbard model

We investigate the thermoelectric properties of a system near a pressure-driven Mott-Hubbard transition. The dependence of the thermopower and the figure of merit on pressure and temperature within a

Quantum dynamical screening of the local magnetic moment in Fe-based superconductors

We have calculated the local magnetic susceptibility of one of the prototypical Fe-based superconductors (LaFeAsO) by means of the local density approximation + dynamical mean field theory as a

Ultrahigh mobility and giant magnetoresistance in the Dirac semimetal Cd3As2.

This work reports a property of Cd3As2 that was unpredicted, namely a remarkable protection mechanism that strongly suppresses backscattering in zero magnetic field and discusses how this may relate to changes to the Fermi surface induced by the applied magnetic field.
