Dr. Zhenglu Li receives 2021 APS Nicholas Metropolis Award for Outstanding Doctoral Thesis Work in Computational Physics:
“For the development and highly-scalable implementation of novel first-principles GW perturbation theory methods to compute electron-phonon coupling with many-electron correlation effects included, and its applications to phonon-induced phenomena in oxide superconductors.“
The paper Phys. Rev. B 34, 5390 (1986) by Mark S. Hybertsen and Steven G. Louie on ab initio GW approach has been selected by Physical Review B as one of its Milestone collection of papers in celebration of its 50th anniversary. Congratulations!
Physical Review B is celebrating its 50th anniversary in 2020. The journal has excelled in front-edge coverage of condensed matter and materials physics research. As part of the celebration, in 2020 the editors are presenting a Milestone collection of papers that have made lasting contributions to condensed matter physics. The Hybertsen-Louie paper is selected for:
“The present PRB Milestone gives a full exposition of the methodology for an original first-principles approach to electronic excitation energies, incorporating the GW approximation directly into solid-state electronic structure theory and demonstrating its advantages for semiconductors and insulators.
Since 1986, the GW approximation has been successfully implemented for the computation of electronic excitation energies in a broad array of materials, including bulk solids, surfaces, and nanostructures such as carbon nanotubes. Many-body perturbation theory has become a mainstream approach in the electronic structure community. The large-scale efforts that have been invested into the development, improvement, and implementation of the GW method have transformed it into the state-of-the-art approach for the accurate description of excitations in weakly correlated molecular systems and solids.”
Our work “Accelerating large-scale excited-state GW calculations on leadership HPC systems” (authored by M. Del Ben, C. Yang, Z. Li, F. H. da Jornada, S. G. Louie, and J. Deslippe) has been selected as a finalist for the 2020 Gordon Bell Prize. In this work, the GPU-accelerated BerkeleyGW has been successfully running at full scale of the Summit machine at Oak Ridge Leadership Computing Facility, utilizing 27,648 GPUs, and reaching 105.9 petaFLOP/s in double precision, 52.7 of the machine peak. A silicon divacancy structure of over 2,700 atoms and over 10,000 electrons is solved with a time-to-solution of 10 minutes.
Prof. Steven G. Louie receives the 2020 Benjamin Lee Professorship Award of the Asian-Pacific Center for Theoretical Physics (APCTP). Congratulations!
Benjamin Lee distinguished professorship is created in honor of Korea’s foremost theoretical physicist, late Benjamin Lee, who had a distinguished career in particle physics theory. The Visiting Professorship is intended to invite a theoretical physicist of international prominence to stay at the APCTP and Korea, and provide opportunities for the domestic scientists and graduate students to interact with a world-caliber theoretical physicist in their fields of study. (Prof. Louie’s visit is delayed due to COVID-19 pandemic.)
