2023 Virtual School on Many-Body Calculations using EPW and BerkeleyGW

[sponce]

Dear Colleagues,

We are happy to announce that on June 5-9, 2023 we will hold the 2023 Virtual School on Many-Body Calculations using EPW and BerkeleyGW.

This school will be the fourth event of a series that started in 2018 with the First International School on Electron-Phonon Physics from First Principles (International Center for Theoretical Physics in Trieste), and continued with a virtual event in 2021, the Virtual School on Electron-Phonon Physics and the EPW Code, and an in-person event in 2022, School on Electron-Phonon Physics from First Principles (The University of Texas at Austin).

This school will introduce participants to advanced ab initio calculations of electron-phonon physics, excited-state approaches including GW and GW-Bethe-Salpeter-equation (GW-BSE), and related materials properties. It will include lectures and hands-on training sessions on the following topics:
• Ab initio many-body methods for electron-phonon physic
• Boltzmann transport equation for carrier transport
• Migdal-Eliashberg theory of phonon-mediated superconductivity
• Phonon-assisted indirect optical absorption
• Polaronic states and self-trapping
• Special displacement method for finite-temperature calculations
• GW and GW-Bethe-Salpeter-equation theories for excited states
• Quasiparticle band structures, optical phenomena, and exciton physics
• GW perturbation theory for electron-phonon coupling with self-energy effects

The school will be based on the EPW, Quantum ESPRESSO, Wannier90, and BerkeleyGW codes. The training sessions will be held on the supercomputers of TACC, the Texas Advanced Computing Center.

Full details on the school and the application process can be found here: https://epw2023.dryfta.com

The application deadline is May 1st, and successful applicants will be notified by May 15.

We are looking forward to seeing you at the school,
Roxana Margine, Zhenglu Li, Hyungjun Lee, Samuel Poncé, Emmanouil Kioupakis, Steven Louie, and Feliciano Giustino.

hello all,
I was trying to compute the drift and hall mobility of cubic boron nitride as given in the tutorial files. I could calculate the hole mobility and spectral decomposition. However as I was trying to calculate the carrier ionized impurity scattering, The calculation crashed which I suspect is the issue with the version of EPW that I am using. I am currently using EPW 7.1 for the calculation. The error message that I get is:

task # 0
from epw_readin : error # 1
Bad line in namelist &inputepw: " ii_g = .true." (error could be in the previous line)
I can post my input file for the calculation if required for the reference.
Thanks
Pravin Karna

Dear Pravin Karna,

As indicated in the tutorial, you need to use QE 7.2.

Best wishes,
Samuel
