Optical Conductivity of Weyl Semimetals and Signatures of the Gapped Semimetal Phase Transition
C. J. Tabert, J. P. Carbotte
The interband optical response of a three-dimensional Dirac cone is linear in photon energy (). Here, we study the evolution of the interband response within a model Hamiltonian…
Optical and Transport Properties in 3D Dirac and Weyl Semimetals
C. J. Tabert, J. P. Carbotte, E. J. Nicol
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 differe…
Anomalous Behaviour in the Magneto-Optics of a Gapped Topological Insulator
Calvin J. Tabert, J. P. Carbotte
The Dirac fermions at the surface of a topological insulator can be gapped by introducing magnetic dopants. Alternatively, in an ultra-thin slab with thickness on the order of the…
Cyclotron Resonance in Topological Insulators: Non-Relativistic Effects
Calvin J. Tabert, J. P. Carbotte
The low-energy Hamiltonian used to describe the dynamics of the helical Dirac fermions on the surface of a topological insulator contains a subdominant non-relativistic (Schrödinge…
Particle-Hole Asymmetry in Gapped Topological Insulator Surface States
Calvin J. Tabert, J. P. Carbotte
We consider the combined effect of a gap and a Zeeman interaction on the helical Dirac fermions which exist on the surface of a topological insulator. Magneto-optical properties, t…
Magnetic Properties of Dirac Fermions in a Buckled Honeycomb Lattice
Calvin J. Tabert, J. P. Carbotte, Elisabeth J. Nicol
We calculate the magnetic response of a buckled honeycomb lattice with intrinsic spin-orbit coupling (such as silicene) which supports valley-spin polarized energy bands when subje…
