WebJun 15, 2024 · The asymmetric DOS strongly influences the energetic of the Mott gap, and the region of orbital-selective Mott phase (OSMP) significantly increases with the increasing NNN hopping amplitude. The Lanczos solver employed in the DMFT calculations is very powerful in finding the critical point of the Mott metal-insulator transition, which has been ...

WebAug 23, 2024 · Recently, there is great interest in multiorbital systems where this transition can be restricted to certain orbitals, leading to an orbital-selective Mott phase (OSMP). Theoretically, the OSMP is widely studied for kinetically decoupled orbitals, but the effect of interorbital hopping remains unclear. WebMotivated by the unexplored complexity of the phase diagrams for multi-orbital Hubbard models, a three-band Hubbard model at integer fillings () with orbital degeneracy lifted partially by crystal field splitting is an… how much robux are in a 25 dollar gift card

WebThe VO2 is a 3d1 electron system that undergoes a reversible metal–insulator transition (MIT) triggered by temperature and characterized by an interplay between orbital, charge and lattice degrees of freedom. The characterization of the MIT features are therefore extremely challenging and powerful investigation tools are required.
