Evaluation of quantum entanglement state between photoelectron spin and emitted photon polarization in spin and polarization resolved XEPECS of
Ryo B. Tanaka, Goro Oohata, Takayuki Uozumi
We theoretically investigated the mechanism of quantum entanglement between the spin of photoelectrons and linear polarization of emitted X-ray photons in the 32…

Excited core-level dependence of entanglement between a photoelectron and an emitted X-ray photon in X-ray inner-shell excitation
Ryo B. Tanaka, Goro Oohata, Takayuki Uozumi
We theoretically investigated how the quantum entanglement between the spin of the photoelectron and the polarization of the emitted X-ray photon depends on the excited core-level,…

Detection of ferroic octupole ordering in -wave altermagnetic rutile-type compounds
Masaichiro Mizumaki, Norimasa Sasabe, Takayuki Uozumi +2
We propose that X-ray absorption and emission magnetic circular dichroism (XAS-MCD and XES-MCD) are promising measurements to directly detect ferroic higher-rank multipoles as cand…
