WebDec 1, 2010 · EPW ( E lectron– P honon coupling using W annier functions) is a program written in Fortran90 for calculating the electron–phonon coupling in periodic systems using density-functional perturbation theory and maximally localized Wannier functions. WebThis feature of EPW leads to fast and accurate calculations of the electron-phonon coupling, and enables the study of the electron-phonon coupling in large and complex systems. ... A. Physical quantities (selfen phon, selfen elec, a2f) In this section we describe some of the physical quantities which can be calculated using EPW. The imaginary part
