Thermoelectric effect on diffusion in the two-dimensional Hubbard model
Martin Ulaga, Jernej Mravlje, Jure Kokalj
We study charge and heat transport in the square lattice Hubbard model at strong coupling using the finite-temperature Lanczos method. We construct the diffusion matrix and estimat…

Finite-temperature properties of the easy-axis Heisenberg model on frustrated lattices
Martin Ulaga, Jure Kokalj, Alexander Wietek +2
Motivated by recent experiments on a compound {displaying Ising-like short-range correlations on the triangular lattice, we study the anisotropic easy-axis spin- Heisenberg mo…
