Pseudogap-induced change in the nature of the Lifshitz transition in the two-dimensional Hubbard model

Maria C. O. Aguiar, Helena BraganÃ§a, Indranil Paul +1

We study the behavior of the density of states and the $B_{1 g}$ nematic susceptibility extracted from Raman response data across the doping-driven Lifshitz transition comparing the…

Low-energy structure and topology of the two-band Hubbard-Kanamori model

Nayara G. GusmÃ£o, GermÃ¡n Blesio, Armando Aligia +3

We investigate the Mott transition in a two-band Hubbard-Kanamori model using Dynamical Mean-Field Theory (DMFT) with the Density Matrix Renormalization Group (DMRG) and the Numeri…

Role of native point defects and Hg impurities in the electronic properties of Bi $_{4}$ I $_{4}$

Gustavo H. Cassemiro, C. David Hinostroza, Leandro Rodrigues de Faria +8

We studied the effects of point defects and Hg impurities in the electronic properties of bismuth iodide (Bi $_{4}$ I $_{4}$ ). Our transport measurements after annealing at different temp…
