The Hubbard model, which augments independent-electron band theory with a single parameter to describe electron-electron correlations, is widely regarded to be the "standard model" of condensed-matter physics. The model has been remarkably successful at addressing a range of correlation phenomena in solids, but it neglects many behaviors that occur in real materials, such as phonons, long-range interactions, and, in its simplest form, multiorbital effects. Here, we use ab initio electronic…

Materials Informatics Approach to the Identification of One-Band Correlated Materials Analogous to the Cuprates
One important yet exceedingly rare property of the cuprate high-temperature superconductors is the presence of a single correlated $d$ band in the low-energy spectrum, leading to the one-band Hubbard
Hubbard models on general lattices: a dynamical cluster approximation approach
The topic of this thesis is simulation of the Hubbard model on general lattices in strongly correlated regime. We approached the task with the dynamical cluster approximation (DCA), a cluster
Quantum algorithms to simulate many-body physics of correlated fermions.
Simulating strongly correlated fermionic systems is notoriously hard on classical computers. An alternative approach, as proposed by Feynman, is to use a quantum computer. Here, we discuss quantum
Characteristics of Transition Metal Oxides
Transition metal oxides (TMOs) are the oxides of d-block elements in the periodic table with partially filled d-sub-shell. They have attracted the research community with their unique and fabulous
Theoretically choosing multifunctional materials
The aim of this paper is to discuss the possibility of theoretically engineering multifunctional nanomaterials. The calculations were performed for 1D and 2D nanomaterials by using results obtained

Orbital-selective mott transitions in the degenerate Hubbard model.
It is demonstrated that separate Mott transitions occur at different Coulomb interaction strengths in general, which merge to a single transition only under special conditions.
