Spectral function analysis on the Holstein polaron problem : extraction of the self-energy and coupling strength, and their implications for angle resolved photoemission spectroscopy
This thesis first reviews and examines the Angle Resolved Photoemission Spectroscopy (ARPES) experiment. It is shown that the spectral density function, familiar from the Green's function method of studying correlated systems, can be directly measured. A model spectral function with a nontrivia...
