Interplay between multipolar spin interactions, Jahn-Teller effect and electronic correlation in a insulator
Dario Fiore Mosca, Leonid V. Pourovskii, Beom Hyun Kim +5
In this work we study the complex entanglement between spin interactions, electron correlation and Janh-Teller structural instabilities in the 5d spin-orb…
Hidden order and multipolar exchange striction in a correlated f-electron system
Leonid V. Pourovskii, Sergii Khmelevskyi
The nature of order in low-temperature phases of some materials is not directly seen by experiment. Such "hidden orders" (HO) may inspire decades of research to identify the mechan…
Ising superconductivity and magnetism in NbSe
Darshana Wickramaratne, Sergii Khmelevskyi, Daniel F. Agterberg +1
Recent studies on superconductivity in NbSe have demonstrated a large anisotropy in the superconducting critical field when the material is reduced to a single monolayer. Motiv…
Comparative ab initio study of the structural, electronic, magnetic, and dynamical properties of LiOsO and NaOsO
Peitao Liu, Jiangang He, Bongjae Kim +4
Despite similar chemical compositions, LiOsO and NaOsO exhibit remarkably distinct structural, electronic, magnetic, and spectroscopic properties. At low temperature, LiOsO…
SrRuO-SrTiO heterostructure as a possible platform for studying unconventional superconductivity in SrRuO
Bongjae Kim, Sergii Khmelevskyi, Cesare Franchini +2
There is intense controversy around the unconventional superconductivity in strontium ruthenate, where the various theoretical and experimental studies suggest diverse and mutually…
Osmates on the verge of a Hund's-Mott transition: The different fates of NaOsO and LiOsO
Daniel Springer, Bongjae Kim, Peitao Liu +6
We clarify the origin of the strikingly different spectroscopic properties of the chemically similar compounds NaOsO and LiOsO. Our first-principle many-body analysis demon…
