EPW is an open-source community code for ab initio calculations of electron-phonon interactions using Density-Functional Perturbation Theory and Maximally Localized Wannier Functions.
EPW is distributed as a core module of the Quantum ESPRESSO materials simulation suite.
The EPW Collaboration includes (in alphabetic order): Kyle Bushick, Feliciano Giustino, Viet-Anh Ha, Samad Hajinazar, Emmanouil Kioupakis, Jon Lafuente-Bartolomé, Hyungjun Lee, Johsua Leveillee, Chao Lian, Jae-Mo Lihm, Francesco Macheda, Roxana Margine, Hitoshi Mori, Hari Paudyal, Samuel Poncé, Weng-Hong Sio, Sabyasachi Tiwari, Marios Zacharias, Xiao Zhang.
The refactoring of EPW toward exascale computing for computational materials design at finite temperatures relevant to designer materials for post-Moore electronics, solar photovoltaics, and energy-efficient lighting is currently supported by the U.S. Department of Energy (DOE), Office of Science, Basic Energy Sciences (BES) under Award DE-SC0020129 (PIs Giustino and Kioupakis). The development of the superconducting module of EPW is currently supported by the U.S. National Science Foundation, under Award DMR-2035518 (PI Margine). The interoperability effort is supported by the U.S. National Science Foundation, under Award OAC-2103991 (PIs Giustino and Margine).
