Berkeley GW illo

11th Annual BerkeleyGW Tutorial Workshop and 6th Berkeley Excited States Conference (BESC2025)

August 18 - 22, 2025

The BerkeleyGW Tutorial Workshop (August 18 - 20) includes lectures and hands-on tutorial sessions on the GW and GW Bethe-Salpeter equation (GW-BSE) approaches using the latest version of BerkeleyGW package (v4.0).

The Workshop will cover theories of GW and GW-BSE methods and beyond, standard and new features of BerkeleyGW, and detailed examples of using the BerkeleyGW in conjunction with various DFT packages.

Training accounts will be available to in-person attendees only for the hands-on sessions using the GPU-accelerated Perlmutter supercomputer.

In tandem with the annual BerkeleyGW Workshop, NERSC will host the 6th Berkeley Excited States Conference (BESC2025). BESC2025 will be a general topical conference with mainly invited talks by experts on recent progress in the theory and applications of ab initio study of quantum many-body effects as well as experiments in excited-state phenomena in materials, showcasing forefront research that involves advanced many-body approaches (e.g., GW, GW-BSE & beyond, DMFT, quantum Monte Carlo, TDDFT, TDGW, etc.), novel experiments, and new science in the excited states.

The US Department of Energy’s Center for Computational Study of Excited-State Phenomena in Energy Materials (C2SEPEM) sponsors both events. 

How to attend

Register online for the Tutorial Workshop and/or BESC2025 Conference. There is no fee to attend.

Note: NERSC will provide training accounts and computation resources for the hands-on session. Training accounts will be allocated prioritizing in-person attendees. Additionally, in-person attendees receive full instructional support during the hands-on session.

The registration deadline for non-NERSC users is August 4.
