RIXS study of strain-tuned coupled valence and spin-state transition in epitaxial films
Yiu-Fung Chiu, Jaewon Choi, Nileena Nandakumaran +7
Strain-tuned thin films provide a model system for controlling coupled valence, spin-state, structura…
Persistent paramagnons in high-temperature infinite-layer nickelate superconductors
Yujie Yan, Ying Chan, Xunyang Hong +25
The recent discovery of high-temperature superconductivity in hole-doped SmNiO, exhibiting the record-high transition temperature among infinite-layer (IL) nickelates, ha…
Unconventional polaronic ground state in superconducting LiTiO
Zubia Hasan, Grace A. Pan, Harrison LaBollita +23
Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interferen…
Doping dependence of 2-spinon excitations in the doped 1D cuprate BaCuO
Jiarui Li, Daniel Jost, Ta Tang +12
Recent photoemission experiments on the quasi-one-dimensional Ba-based cuprates suggest that doped holes experience an attractive potential not captured using the simple Hubbard mo…
Unified Description of Charge Density Waves in Electron- and Hole-doped Cuprate Superconductors
Jaewon Choi, Sijia Tu, Abhishek Nag +7
High-temperature cuprates superconductors are characterised by the complex interplay between superconductivity (SC) and charge density wave (CDW) in the context of intertwined comp…
Emergence of interfacial magnetism in strongly-correlated nickelate-titanate superlattices
Teguh Citra Asmara, Robert J. Green, Andreas Suter +21
Strongly-correlated transition-metal oxides are widely known for their various exotic phenomena. This is exemplified by rare-earth nickelates such as LaNiO, which possess int…
Electronic and magnetic excitations in LaNiO
Xiaoyang Chen, Jaewon Choi, Zhicheng Jiang +13
The striking discovery of high-temperature superconductivity (HTSC) of 80 K in a bilayer nickelate LaNiO under a moderately high pressure of about 14 GPa ignited a new…
Resolving the Orbital Character of Low-energy Excitations in Mott Insulator with Intermediate Spin-orbit Coupling
K. von Arx, P. Rothenbühler, Qisi Wang +10
Multi-band Mott insulators with moderate spin-orbit and Hund's coupling are key reference points for theoretical concept developments of correlated electron systems. The ruthenate…
Non-local features of the spin-orbit exciton in Kitaev materials
Blair W. Lebert, Subin Kim, Beom Hyun Kim +7
A comparative resonant inelastic x-ray scattering (RIXS) study of three well-known Kitaev materials is presented: -LiIrO, NaIrO, and -RuCl. Despite simila…
Identification of a Critical Doping for Charge Order Phenomena in Bi-2212 Cuprates via RIXS
Haiyu Lu, Makoto Hashimoto, Su-Di Chen +16
Identifying quantum critical points (QCPs) and their associated fluctuations may hold the key to unraveling the unusual electronic phenomena observed in cuprate superconductors. Re…
Weak-signal extraction enabled by deep-neural-network denoising of diffraction data
Jens Oppliger, M. Michael Denner, Julia Küspert +20
Removal or cancellation of noise has wide-spread applications for imaging and acoustics. In every-day-life applications, denoising may even include generative aspects, which are un…
Novel magnetic excitations beyond the single- and double-magnons
Hebatalla Elnaggar, Abhishek Nag, Maurits W. Haverkort +2
Conventional wisdom suggests that one photon that carries one unit of angular momentum can change the spin angular momentum of a magnetic system with one unit (delta Ms = +-1) at m…
Signature of quantum criticality in cuprates by charge density fluctuations
R. Arpaia, L. Martinelli, M. Moretti Sala +17
The universality of the strange metal phase in many quantum materials is often attributed to the presence of a quantum critical point (QCP), a zero-temperature phase transition rul…
