1Electron–phonon physics from first principles using the EPW code显示文摘EPW is an open-source software for ab initio calculations of electron–phonon interactions and related materials properties.The code combines density functional perturbation theory and maximally localized Wannier functions to efficiently compute electron–phonon coupling matrix elements,and to perform predictive calculations of temperature-dependent properties and phonon-assisted quantum processes in bulk solids and low-dimensional materials.Here,we report on significant developments in the code since 2016,namely:a transport module for the calculation of charge carrier mobility under electric and magnetic fields using the Boltzmann transport equation;a superconductivity module for calculations of phonon-mediated superconductors using the anisotropic multi-band Eliashberg theory;an optics module for calculations of phonon-assisted indirect transitions;a module for the calculation of small and large polarons without supercells;and a module for calculating band structure renormalization and temperature-dependent optical spectra using the special displacement method.For each capability,we outline the methodology and implementation and provide example calculations.Hyungjun Lee Samuel Poncé Kyle Bushick Samad Hajinazar Jon Lafuente-Bartolome Joshua Leveillee Chao Lian Jae-Mo Lihm Francesco Macheda Hitoshi Mori Hari Paudyal Weng Hong Sio Sabyasachi Tiwari Marios Zacharias Xiao Zhang Nicola Bonini Emmanouil Kioupakis Elena R.Margine Feliciano Giustino 2023npj Computational Materials2023,,1:0
