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…
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…
Possibility of ferro-octupolar order in BaCaOsO assessed by X-ray magnetic dichroism measurements
Goro Shibata, Naomi Kawamura, Jun Okamoto +9
Localized electrons in a cubic crystal field possess multipoles such as electric quadrupoles and magnetic octupoles. We studied the cubic double perovskite BaCaOsO c…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Giant X-ray circular dichroism in a time-reversal invariant altermagnet
Jun Okamoto, Ru-Pan Wang, Yen-Yi Chu +13
X-ray circular dichroism, arising from the contrast in X-ray absorption between opposite photon helicities, serves as a spectroscopic tool to measure the magnetization of ferromagn…
