  •  May 24th, 2022: We can still accept a few participants. Registrations will be closed on June 3rd, 2022.
  •  May 1st, 2022: The registration fee has been set to 817.60€ for the two weeks. It covers expenses for a shared double room and all the meals.
  •  February 1st, 2022: We currently organise the 2022 edition of the ISTPC. We confirm that it will take place in Aussois from June 19th to July 2nd, 2022. The list of participants and the waiting list will be updated soon. Some of you sent us emails either to confirm their participation or to register to this new edition. Do not worry if you have not yet received an answer (the registration process has been suspended until now). We will come back to you as soon as possible. Looking forward to seeing many of you in Aussois.
  •  January 21st, 2021: As most conference/workshop organisers, we decided to postpone ISTPC to 2022. We booked the center in Aussois for the period June 19th – July 2nd, 2022. To reduce the frustration, we decided to organise a “softer” online version of the school. It will consist of a series of two-hour lectures. One lecture will be given every week from the end of March until mid-June 2021.
  •  June 15th, 2020: We expect the third edition of ISTPC to take place in Aussois in the period April 11th-24th, 2021.
  •  April 22nd, 2020: Due to the coronavirus, ISTPC will be postponed to 2021 (probably in March or April). We will keep you updated about the definitive dates. We do hope that all the registered participants (and their relatives) are safe and that they will be able to come to Aussois in 2021.
  •  December 6th, 2019: ISTPC has been selected for being part of the 2020 CECAM flagship program. Both French South-West and Rhône-Alpes nodes [CECAM-FR-GSO and CECAM-FR-RA] will provide financial support to the summer school.

First Announcement


Dear colleagues,

we are glad to announce that the third edition of the International summer School in electronic structure Theory “electron correlation in Physics and Chemistry” (ISTPC) will take place in Aussois (Savoie, France) from the 14th to the 27th of June 2020.

This two-week summer school is open to Master/PhD students, post-docs and researchers using or developing methods for electronic structure calculations. One of the motivation for organizing such a school is to stimulate discussions between chemists and physicists on the problem of electron correlation.

The number of participants is limited to 40 on a first come – first served basis. The registration webpage is under construction.

If you wish to be on the pre-registration list (and you want to get updated about ISTPC) you just have to send an email to istpcVEDunistra.fr (replace VED by @).

ISTPC 2020 is organized with the support of the national research groups (GDRs) NBODY and REST.

More scientific details are given below.

Looking forward to seeing many of you at ISTPC 2020!

Emmanuel Fromager, Vincent Robert, Julien Toulouse, Pina Romaniello, and Pierre-François Loos.

Scientific Program


The following topics will be covered:

Second quantization, density functional theory (DFT), Reduced density-matrix functional theory (RDMFT), time-dependent DFT (TD-DFT), Hartree-Fock (HF) and post-HF methods, multi-configurational self-consistent field method, multi-reference perturbation theory, physics of electron correlation, model Hamiltonians, linear response theory, basics in solid-state physics, Green’s functions, Quantum Monte Carlo (QMC), density matrix renormalization group method (DMRG), GW method, Bethe-Salpeter equation, Dynamical Mean Field Theory (DMFT), Density-matrix functional quantum embedding, mathematical aspects of electronic structure theory.

Three one-hour-and-half lectures will be given every day (two in the morning and one in the afternoon). Some tutorial sessions will be scheduled so that the participants can derive the key equations presented during the lectures.
