Novel theoretical approach in photoemission spectroscopy: application to isotope effect and boron-doped diamond
Jifeng Yu, Kai Ji, Keiichiro Nasu
A new path-integral theory is developed to calculate the photoemission spectra (PES) of correlated many-electron systems. The application to the study on Bi2Sr2CaCu2O8 (Bi2212) and…

Theoretical study on isotopic shift in angle-resolved photoemission spectra of Bi2Sr2CaCu2O8
Kai Ji, Keiichiro Nasu
We develop a path-integral theory to study the angle-resolved photoemission spectra (ARPES) of high-T_c superconductors based on a two-dimensional model for the CuO2 conduction pla…

Isotopic shift in angle-resolved photoemission spectra of Bi2Sr2CaCu2O8 due to quadratic electron-phonon coupling
Kai Ji, Keiichiro Nasu
In connection with the experiment on oxygen isotope effect of Bi2Sr2CaCu2O8 with the angle-resolved photoemission spectroscopy (ARPES), we theoretically study the isotope-induced b…
