Pseudogap-induced change in the nature of the Lifshitz transition in the two-dimensional Hubbard model
Maria C. O. Aguiar, Helena Bragança, Indranil Paul +1
We study the behavior of the density of states and the 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. Gusmão, Germán 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 BiI
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 (BiI). Our transport measurements after annealing at different temp…
Electronic and magnetic properties of (NdNiO)/(LaSrMnO) superlattices: a DFT+U perspective
Henrique M. M. Cardoso, Maria C. O. Aguiar, Cinthia Piamonteze +1
The electronic and magnetic properties of NdNiO (NNO) thin films are very sensitive to epitaxial strain and to the proximity to ferromagnetic oxides. In this work, we investiga…
Bound states in two-dimensional Fermi systems with quadratic band touching
Flávio L. N. Santos, Mônica A. Caracanhas, M. C. O. Aguiar +1
The formation of bound states between mobile impurity particles and fermionic atoms has been demonstrated in spin-polarized Fermi gases with attractive interspecies interaction. We…
