Surface Kondo Effect and Non-Trivial Metallic State of the Kondo Insulator YbB12
Kenta Hagiwara, Yoshiyuki Ohtsubo, Masaharu Matsunami +13
A synergistic effect between strong electron correlation and spin-orbit interaction (SOI) has been theoretically predicted to result in a new topological state of quantum matter on…
Strong Correlation Effects of A-site Ordered Perovskite CaCu3Ti4O12 revealed by Angle-Resolved Photoemission Spectroscopy
