Selective coupling of high-order phonons in La2-xSrxCuO4
Ke-Jun Xu, Paulina Majchrzak, Nathan Giles-Donovan +14
In crystals and molecules with strong coupling between the charge carriers and atomic vibrations, high order harmonics of the vibrational excitations can be observed with intensity…
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…
