The Mott insulator CaRuOis a paradigmatic example among transition metal oxides, where the interplay of charge, spin, orbital, and lattice degrees of freedom leads to competing quantum phases. In this paper, we focus on and review some key aspects, from the underlying physical framework and its basic properties, to recent theoretical efforts that aim to trigger unconventional quantum ground states, using several external parameters and stimuli. Using first-principle calculations, we demonstrate that CaRuOshows a spin splitting in the reciprocal space, and identify it as an altermagnetic candidate material.

The kagome network is a unique platform that harbors a diversity of special electronic states due to its inherent band structure features comprising Dirac cones, van Hove singularities, and flat bands. Some kagome-based metals have recently been found to exhibit favorable properties, including superconductivity, charge order, and signatures of an anomalous Hall effect. The kagome system ScVSn is a promising candidate for studying the emergence of an unconventional charge order and accompanying effects.

Kagome lattice has been actively studied for the possible realization of frustration-induced two-dimensional flat bands and a number of correlation-induced phases. Currently, the search for kagome systems with a nearly dispersionless flat band close to the Fermi level is ongoing. Here, by combining theoretical and experimental tools, we present ScMnAlSi as a novel realization of correlation-induced almost-flat bands in the kagome lattice in the vicinity of the Fermi level.

Ferromagnetic (FM) states with high Curie temperatures () and strong spin-orbit coupling (SOC) are indispensable for the long-sought room-temperature quantum anomalous Hall (QAH) effects. Here, we propose a two-dimensional (2D) iron-based monolayer MgFeP that exhibits a notably high FM (about 1525 K) along with exceptional structural stabilities. The unique multiorbital nature in MgFeP, where localized and orbitals coexist with itinerant and orbitals, renders the monolayer a Hund's metal and in an orbital-selective Mott phase (OSMP).

Mott physics plays a critical role in materials with strong electronic correlations. Mott insulator-to-metal transition can be driven by chemical doping, external pressure, temperature and gate voltage, which is often seen in transition metal oxides with electrons near the Fermi energy (e.g.
