Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
The study uses time‑resolved resonant inelastic X‑ray scattering to monitor how collective magnetic excitations (paramagnons) in an optimally electron‑doped cuprate superconductor…
Interlayer Five-Spin Polaron in Superconducting Bilayer Nickelates
Jiarui Li, Christopher T. Parzyck, Eder G. Lomeli +19
The discovery of high- superconductivity in Ruddlesden-Popper nickelates has sparked substantial effort towards understanding unconventional electronic states beyond a traditi…
Spectroscopic evidence for a molecular orbital Kondo insulator
Ke-Jun Xu, Kuan H. Hsu, Nathan Giles-Donovan +13
A Kondo insulator (KI) is a prototypical example of a highly entangled phase of matter, where many-body interactions between local moments and delocalized electrons engender the no…
Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…
Biaxial Strain Control of Helimagnetism via Chemical Expansion in Thin Film SrFeO3
Jennifer Fowlie, Jiarui Li, Danilo Puggioni +15
We demonstrate control of helimagnetic order in biaxially strained SrFeO3 thin films using neutron diffraction and resonant soft x-ray scattering. SrFeO3, a negative charge-transfe…
Enhanced superconducting correlations in the Emery model and its connections to strange metallic transport and normal state coherence
Sijia Zhao, Rong Zhang, Wen O. Wang +5
Numerical evidence for superconductivity in the single-band Hubbard model is elusive or ambiguous despite extensive study, raising the question of whether the single-band Hubbard m…
