Welcome to the Palaiseau Theoretical Spectroscopy Group

The theoretical spectroscopy group develops theoretical and numerical approaches for the calculation of electronic properties, in particular many-body effects in electronic spectra. The research profile of the group has been defined in 2000; it is centred on the theoretical description of electronic excitations from first principles. The global aim is to design techniques which can be applied to a wide range of systems, from small clusters to bulk materials, from metals to insulators. These developments comprise a part of fundamental theory, the design of approximations, the implementation of the new theory in ab initio computer codes, testing and benchmarking of the results, and applications to interesting materials. Applications often combine fundamental questions and technological interest, examples being materials for data storage, for solar energy production or optoelectronics.


  • 1 October 2023      New PhD student :: Sarbajit

    Sarbajit Dutta joined the group as a PhD student, under the supervision of Matteo and Lucia.

  • 1 October 2023      New master students

    We are glad to welcome two visiting master students: Abezu Agegnehu from Ethiopia and Newman Amoyaw from Ghana. They have a Polytechnique fellowship for a two-months internship with us.

  • 15 September 2023      New postdoc :: Maram Ali Ahmed

    We welcome the new postdoc in the group, Maram Ali Ahmed. Like Fatema, she came in 2022 for a 3-month internship (thanks to the French embassy in Sudan and the Institut fran├žais of Sudan). She is now the recipient of the Schlumberger Foundation fellowship, working with Matteo on Metavalent bond materials.

  • 1 September 2023      New postdoc :: Kevin Leveque-Simon

    Kevin has now joined Valerie's team to work on non-linear processes.

  • 1 July 2023      Vitaly Gorelov joins the group

    Vitaly, so far post-doc in our group, won the CNRS concour and is now a CNRS permanent researcher. Welcome!
