In-gap band in the one-dimensional two-orbital Kanamori-Hubbard model with inter-orbital Coulomb interaction
N. Aucar Boidi, H. Fernández García, Y. Núñez-Fernández +1
We study the electronic spectral properties at zero temperature of the one-dimensional (1D) version of the degenerate two-orbital Kanamori Hubbard model (KHM), one of the well esta…
Novel subbands in the doped two-orbital Kanamori-Hubbard model
K. Hallberg, Y. Núñez-Fernández
We calculate and resolve with unprecedented detail the local density of states (DOS) and momentum-dependent spectral functions at zero temperature of one of the key models for stro…
Zero-site DMRG and the optimal low-rank correction
Yuriel Núñez-Fernández, Gonzalo Torroba
A zero-site density matrix renormalization algorithm (DMRG0) is proposed to minimize the energy of matrix product states (MPS). Instead of the site tensors themselves, we propose t…
State-of-the-art techniques for calculating spectral functions in models for correlated materials
K. Hallberg, D. J. García, Pablo S. Cornaglia +2
The dynamical mean field theory (DMFT) has become a standard technique for the study of strongly correlated models and materials overcoming some of the limitations of density funct…
