This event is a workshop, with hands-on user sessions, on the GW and GW-BSE approaches using the BerkeleyGW package will be held November 22-23, 2013, at the Lawrence Berkeley National Lab in the NERSC Facility in Oakland, California. The target audience for the workshop are graduate students, postdocs, and researchers who are interested in learning about or sharpening their skills onab initiocalculations of many-electron effects in excited-state properties of condensed matter.
The BerkeleyGW Package 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 nanostructures such as slabs, sheets, tubes, wires, and dots. The package takes as input the mean-field results from commonly available electronic structure codes such as the Kohn-Sham DFT eigenvalues and eigenvectors computed with PARATEC, PARSEC, Quantum ESPRESSO, SIESTA, Octopus, or TBPW (aka EPM).
The two-day workshop will cover basic GW/BSE theory, features of the BerkeleyGW package, and detailed examples of using the BerkeleyGW package in conjunction with the above mentioned DFT packages. In particular, connections to the real-space code PARSEC and planewave code PARATEC are made.
There is no registration fee, but attendees must apply. (UPDATE: Attendance at workshop is at capacity. No more applications will be accepted).
