Orbital selective mott phase
WebSep 7, 2024 · An important characteristics of the models is that the orbitals are kinetically coupled, i.e., hybridized, to each other, which makes the orbital-selective Mott phase especially nontrivial. A U (1) slave-spin method was used to analyze the model with nonzero orbital-level splittings. WebJun 29, 2024 · Another example of competing interactions is the orbital-selective Mott phase (OSMP) (22, 23). In multiorbital systems, this effect can lead to the selective localization of electrons on some orbitals. The latter coexist with itinerant bands of mobile electrons. This unique mixture of localized and itinerant components in multiorbital …

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. In this work, …
