Analysis of the magnetic response of the edge-sharing chain cuprate LiCuO within TMRG
Evgeny Plekhanov, Adolfo Avella, Ferdinando Mancini
It is widely accepted that the low-energy physics in edge-sharing cuprate materials has one-dimensional (1D) character. The relevant model to study such systems is believed to be t…
Entanglement Properties and Phase Diagram of the Two-Orbital Atomic Hubbard Model
A. Avella, F. Mancini, G. Scelza +1
We study the two-orbital Hubbard model in the limit of vanishing kinetic energy. The phase diagram in the plane, with and denoting the interorbital hybridization and…
The two-orbital Hubbard model and the OSMT
Adolfo Avella, Ferdinando Mancini, Satoru Odashima +1
We analyze the two-orbital Hubbard model by means of the Composite Operator Method with the aim at studying the phenomenon of orbital selective Mott transition (OSMT). The model co…
