Theory of Cold Molecules : Structure, Dynamics, Reactivity (English Version)


Welcome to the homepage of the Theomol team ! Our research consists in the development of theoretical, methodological and numerical methods to study the structure and dynamics at very low energies of atoms and small molecules in gas phase, as well as their interactions with electromagnetic fields.




Last news :

  • Nadia Bouloufa has been awarded the grade of "Chevalier dans l’ordre des Palmes Académiques" by decree of January 11, 2017. Congratulations :) :) :) !!!
  • XiaoDong Xing has joined our team since October 2, 2017 for a PhD thesis. Welcome !
  • Laurent Wiesenfeld (IPAG Grenoble) will join our team for a long-period visit starting January 2018
  • Master 2 Internship position (March - June 2018) : Microwave shielding of ultracold dipolar molecules. A 3-years PhD position will follow the successful completion of the internship. The PhD position will start September 1st, 2018.
  • Publication of "Adimensional theory of shielding in ultracold collisions of dipolar rotors", M. L. González-Martínez, J. L. Bohn, G. Quéméner, Phys. Rev. A 96, 032718 (2017).
  • We got an ANR grant "Jeunes Chercheuses et Jeunes Chercheurs" FEW2MANY-SHIELD.


The Theomol team is composed by five permanent members, Nadia Bouloufa, Olivier Dulieu (team leader), Goulven Quéméner, Maurice Raoult, Romain Vexiau, as well as two emeritus researchers, Anne Crubellier and Eliane Luc, two PhD students, Adrien Devolder and XiaoDong Xing, a post-doctoral researcher, Humberto Da Silva Jr, and three long-period associated researchers, Ioan Schneider, Laurent Wiesenfeld, Jean-François Wyart.

The subjects tackled by the group include the formation, dynamics and control of atoms and simple molecules in thermal and quantum gases, as well as more complex systems such as triatomic molecules and molecular ions. Such few-body systems are prototypes both for theoretical models and experimental projects. The ultimate goal of such research is to achieve a complete control of such few-body systems using external electromagnetic fields, which would be accomplished through a detailed knowledge of their structure and dynamics.

One essential aspect of our team’s activity is to approach such problems both from the "structure" point of view, using quantum-chemistry and asymptotic methods, and the "dynamics" point of view, using a number of different approaches including DVR-grid methods, coupled-channel (time-independent) methods, multi-channel quantum defect theory and time-dependent wave-packet propagation methods. The development of these two complementary approaches, structure and dynamics, is one of the essential assets of our team and each year leads to several publications, the establishment of new collaborations, and offers for PhD theses, postdoctoral and Master studies.
