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…
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…
Time-resolved X-ray Spectroscopy from the Atomic Orbital Ground State Up
Daniel Jost, Eder G. Lomeli, Ta Tang +6
X-ray spectroscopy has been a key method to determine ground and excited state properties of quantum materials with atomic specificity. Now, new x-ray facilities are opening the do…
