Impact of strong electronic correlations on altermagnets: the case of NiS2
Ina Park, Turan Birol, Antoine Georges +1
One of the distinguishing features of an altermagnet is that its spin-up and spin-down bands display a nodal momentum-dependent splitting even in the absence of spin-orbit coupling…
Pressure-induced thermal expansion anomalies in dhcp iron hydride associated with magnetoelastic coupling
Yuichiro Mori, Katsutoshi Aoki, Masahiro Takano +7
Iron hydride with a double hexagonal close-packed structure (dhcp-FeH) undergoes a ferromagnetic-paramagnetic transition without changing its crystal structure. Despite its r…
Neural-Network Quantum Embedding Solvers for Correlated Materials
Agnes Valenti, Ina Park, Antoine Georges +2
Quantum impurity solvers are the computational bottleneck of quantum embedding approaches to correlated materials, such as dynamical mean-field theory (DMFT). We show that neural n…
Clean realization of the Hund physics near the Mott transition: under pressure
Ina Park, Bo Gyu Jang, Dong Wook Kim +2
Strong correlation effects caused by Hund's coupling have been actively studied during the past decade. Hund's metal, strongly correlated while far from the Mott insulating limit,…
Origin of superionic state in Earth's inner core
Ina Park, Yu He, Ho-kwang Mao +2
Earth's inner core (IC) serves as a reservoir for volatile elements, which significantly affects its behavior and properties. Recent studies suggest that superionicity can be obser…
Superconductivity of metastable dihydrides at ambient pressure
Heejung Kim, Ina Park, J. H. Shim +1
Hydrogen in metals is a significant research area with far-reaching implications, encompassing diverse fields such as hydrogen storage, metal-insulator transitions, and the recentl…
