7th BerkeleyGW Tutorial Workshop

We would like to announce the 7th Annual BerkeleyGW Tutorial Workshop, with hands-on user sessions on the GW and GW Bethe-Salpeter equation (GW-BSE) approaches using the BerkeleyGW package. The Tutorial Workshop will be held January 4-6, 2021, Pacific standard time (PST), in a virtual online format this year.  The target participants for the Workshop are graduate students, postdocs, and researchers who are interested in learning about or sharpening their skills on ab initio calculations of many-electron effects in excited-state properties of condensed matter.

The BerkeleyGW Package (http://www.berkeleygw.org) is a set of computer codes that calculates the quasiparticle properties and the optical responses of a large variety of materials from bulk crystals to molecules and 2D/1D materials such as slabs, sheets, tubes, wires, and dots, and is applicable to insulating, metallic, and semi-metallic systems. The package takes as input the mean-field results such as the Kohn-Sham DFT eigenvalues and eigenvectors computed with commonly available electronic structure codes including ABINIT, Octopus, PARATEC, PARSEC, Quantum ESPRESSO, RMGDFT, SIESTA, TBPW, etc.

The Workshop will cover basic GW and BSE theory, standard and new features of the BerkeleyGW package, and detailed examples of using the BerkeleyGW package in conjunction with some of the above mentioned DFT packages.

2nd Berkeley Excited States Conference (BESC2021)

In tandem to the BerkeleyGW Workshop, on January 7-8, 2021 PST, we will host a two-day virtual conference (online via Zoom): the Berkeley Excited States Conference 2021 (BESC2021).  BESC2021 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 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.) and new science in the excited state. 

Both events are sponsored by DOE’s Center for Computational Study of Excited-State Phenomena in Energy Materials (C2SEPEM). Please find more information along with registration (no fees, but space is limited for hands-on tutorial sessions) at: https://workshop.berkeleygw.org/
