Collective nature of orbital excitations in layered cuprates in the absence of apical oxygens
Leonardo Martinelli, Krzysztof Wohlfeld, Jonathan Pelliciari +19
We have investigated the 3d orbital excitations in CaCuO2 (CCO), Nd2CuO4 (NCO), and La2CuO4 (LCO) using high-resolution resonant inelastic x-ray scattering. In LCO they behave as w…
Charge ordering in Ir dimers in the ground state of BaAlIrO
Vamshi M. Katukuri, Xingye Lu, D. E. McNally +8
It has been well established experimentally that the interplay of electronic correlations and spin-orbit interactions in Ir and Ir oxides results in insulating J$_{\r…
Spin dynamics in NaFeAs and NaFeCuAs probed by resonant inelastic X-ray scattering
Yu Song, Weiyi Wang, Eugenio Paris +11
The parent compounds of iron-based superconductors are magnetically-ordered bad metals, with superconductivity appearing near a putative magnetic quantum critical point. The presen…
Strain-engineering of the charge and spin-orbital interactions in Sr2IrO4
Eugenio Paris, Yi Tseng, Ekaterina M. Pärschke +16
In the high spin-orbit coupled Sr2IrO4, the high sensitivity of the ground state to the details of the local lattice structure shows a large potential for the manipulation of the f…
Novel Cu-based dz2 order at a YBa2Cu3O7/ manganite interface
Roxana Gaina, Christopher W. Nicholson, Maxime Rumo +12
The interplay of nearly degenerate orders in quantum materials can lead to a myriad of emergent phases. A prominent case is that of the high-Tc cuprates for which the relationship…
Electronic Localization in CaVO3 Films via Bandwidth Control
Daniel E. McNally, Xingye Lu, Jonathan Pelliciari +11
Understanding and controlling the electronic structure of thin layers of quantum materials is a crucial first step towards designing heterostructures where new phases and phenomena…
Orbital dynamics during an ultrafast insulator to metal transition
Sergii Parchenko, Eugenio Paris, Daniel McNally +20
Phase transitions driven by ultrashort laser pulses have attracted interest both for understanding the fundamental physics of phase transitions and for potential new data storage o…
Anisotropic magnetic excitations and incipient Néel order in Ba(FeMn)As
Fernando A. Garcia, Oleh Ivashko, Daniel E. McNally +7
It is currently understood that high temperature superconductivity (SC) in the transition metal substituted iron arsenides Ba(Fe)As is promoted b…
Orbital-selective confinement effect of Ru orbitals in SrRuO ultrathin film
Soonmin Kang, Yi Tseng, Beom Hyun Kim +11
The electronic structure of SrRuO thin film with thickness from 50 to 1 unit cell (u.c.) is investigated via the resonant inelastic x-ray scattering (RIXS) technique at the O K…
Site selective spin and orbital excitations in Fe3O4
H. Elnaggar, R. Wang, S. Lafuerza +10
is a mixed-valence strongly correlated transition metal oxide which displays the intriguing metal to insulator Verwey transition. Here we investigate the electronic and m…
Decoupling carrier concentration and electron-phonon coupling in oxide heterostructures observed with resonant inelastic x-ray scattering
D. Meyers, Ken Nakatsukasa, Sai Mu +19
We report the observation of multiple phonon satellite features in ultra thin superlattices of form SrIrO/SrTiO using resonant inelastic x-ray scattering. As the valu…
Strain-Engineering Mott-Insulating LaCuO
O. Ivashko, M. Horio, W. Wan +15
The transition temperature of unconventional superconductivity is often tunable. For a monolayer of FeSe, for example, the sweet spot is uniquely bound to titanium-o…
