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 development of EPW is led and coordinated by Sabyasachi Tiwari, Samuel Poncé, Emmanouil Kioupakis, Roxana Margine, and Feliciano Giustino
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).
