Magnetic excitations and absence of charge order in the van der Waals ferromagnet FeGeTe
V. K. Bhartiya, T. Kim, J. Li +12
Understanding the ground state of van der Waals (vdW) magnets is crucial for designing devices leveraging these platforms. Here, we investigate the magnetic excitations and charge…
Coupling of Electronic Transitions to Ferroelectric Order in a 2D Semiconductor
Chun-Ying Huang, Daniel G. Chica, Zhi-Hao Cui +16
A ferroelectric material often exhibits a soft transvers optical (TO) phonon mode which governs it phase transition. Charge coupling to this ferroelectric soft mode may further med…
Superconductivity in the parent infinite-layer nickelate NdNiO
C. T. Parzyck, Y. Wu, L. Bhatt +14
We report evidence for superconductivity with onset temperatures up to 11 K in thin films of the infinite-layer nickelate parent compound NdNiO. A combination of oxide molecula…
Capping effects on spin and charge excitations in parent and superconducting Nd1-xSrxNiO2
S. Fan, H. LaBollita, Q. Gao +19
Superconductivity in infinite layer nickelates Nd1-xSrxNiO2 has so far been achieved only in thin films raising questions on the role of substrates and interfaces. Given the challe…
Highly Tunable Ru-dimer Molecular Orbital State in 6H-perovskite BaMRuO
Bo Yuan, Beom Hyun Kim, Qiang Chen +7
Molecular orbital (MO) systems with clusters of heavy transition metal (TM) ions are one of the most important classes of model materials for studying the interplay between local p…
Magnetically propagating Hund's exciton in van der Waals antiferromagnet NiPS3
W. He, Y. Shen, K. Wohlfeld +9
Magnetic van der Waals (vdW) materials have opened new frontiers for realizing novel many-body phenomena. Recently NiPS3 has received intense interest since it hosts an excitonic q…
Nature of excitons and their ligand-mediated delocalization in nickel dihalide charge-transfer insulators
Connor A. Occhialini, Yi Tseng, Hebatalla Elnaggar +7
The fundamental optical excitations of correlated transition-metal compounds are typically identified with multielectronic transitions localized at the transition-metal site, such…
Elementary excitations of single-photon emitters in hexagonal Boron Nitride
Jonathan Pelliciari, Enrique Mejia, John M. Woods +8
Single-photon emitters serve as building blocks for many emerging concepts in quantum photonics. The recent identification of bright, tunable, and stable emitters in hexagonal boro…
