| Title: | Dynamical spin conductivity of the Heisenberg antiferromagnetic checkerboard lattice |
| Authors: | Antônio Sérgio Teixeira Pires |
| Abstract: | We study spin transport on the anisotropic antiferromagnetic checkerboard lattice with a Dzyaloshinskii-Morya interaction. The dynamical spin conductivity is calculated using a Kubo formula. The Drude weight is also calculated as a function of temperature. The Drude weight vanishes at T = 0, but is finite for T > 0. A finite Drude weight indicates an ideal conductor, which we refer to as ballistic transport. |
