2026 School on Electron-Phonon Physics and Many-body Perturbation Theory

Administration

Description

An ICTP Meeting

An advanced school on first-principles methods for electron-phonon physics and excited-state phenomena, featuring theory lectures and hands-on training with EPW, Quantum ESPRESSO, Wannier90, xARPES, elphbolt and Abinit on modern HPC systems.

Building on a successful series of electronic-structure schools, this event trains graduate students, postdocs, and researchers in cutting-edge computational methods for transport, optical, and superconducting properties.
Topics include density-functional perturbation theory, GW quasiparticle calculations, and Bethe-Salpeter equation (BSE) approaches, with applications to semiconductors, 2D materials, superconductors, and topological systems.

The program combines morning lectures on advanced theory with afternoon hands-on tutorials using TACC supercomputers.

We plan to welcome participants at ICTP on Sunday, June 14th 2026; start the school on the morning of Monday, June 15; and conclude on Sunday, June 21 in the afternoon.

**More information are available here

Topics to be covered during the school include:

Quantum Espresso
Maximally-localized Wannier functions
Theory of electron-phonon coupling
Superconductivity
Carrier transport
Spectral function and Koopmans
ARPES extraction
Phonon-mediated superconductivity
Optical spectra including direct and phonon-assisted optical transitions

Special displacement method for finite-temperature calculations
GW quasiparticle band structures
Excitons and Bethe-Salpeter equation
GW perturbation theory
Jupyter Notebooks with EPWpy
