Crystal field excitations in rattling clathrate CeBaAuSi
Michelangelo Tagliavini, Federico Mazza, Xinlin Yan +6
We investigate the local crystal-field environment of cerium in the clathrate compound CeBaAuSi (Ce-BAS) using resonant inelastic x-ray scattering (RIXS) and magneti…

Quantum Fisher information in a strange metal
Federico Mazza, Sounak Biswas, Xinlin Yan +5
A strange metal is an exotic state of correlated quantum matter; intensive efforts are ongoing to decipher its nature. Here we explore whether the quantum Fisher information (QFI),…
