Scientific Calendar Event



Description
An ICTP meeting in person

A vast ecosystem of electronic structure methods and software populate the theoretical and computational scientific landscape. Excited state applications in solids and molecules are amongst the most employed ones, spreading from physics to chemistry to biology and beyond. However, the accurate modeling of excited state properties in realistic systems remains an open-challenge due to the complexity of the underlying electronic structure.

This workshop will gather code developers from several electronic structure packages  (Quantum Espresso, Orca, DFTB+, LiÔ, SIESTA, Newton-X, Yambo, BigDFT, Onetep, SHARC, Octopus, etc) involved in excited state method developments and applications. We will focus our discussions on practical challenges, implementation bottlenecks, state-of-the-art methodological developments, as well as limitations in real systems applications. 

A balanced audience of varied expertise (Post-Hartree-Fock, TDDFT, GW, Bethe-Salpeter, Excited State Adiabatic and non-Adiabatic dynamics) and working on diverse implementations (e.g. Gaussian basis, plane-waves, wavelets), will provide a fertile environment for exchanging ideas, sharing and comparing common problems and possible solutions, and exposing researchers working in the field to the variety of novel developments and features these codes have to offer.

Topics:
  • Light-Matter Interactions
  • Spectroscopic characterization of excited states
  • Ultrafast spectroscopy for excitation dynamics
  • Charge separation and transfer
  • Relaxation processes
  • Adiabatic and non-adiabatic excited state dynamics
  • Post-Hartree-Fock methods
  • Time Dependent Density Functional Theory
  • GW, Bethe-Salpeter and many-body perturbation methods
  • Machine learning for excited states
  • Quantum/Classical methods for ultrafast photoinduced dynamical processes
Applicants are encouraged to submit an abstract for a poster presentation.
