The Quantum Dynamics team is centered around the study of strongly out-of-equilibrium dynamics of aggregates and nano-objects. The reference method is Density Functional Theory (DFT) in its “Time-Dependent” version (TDDFT). The latter method, in its standard form, is essentially an effective mean-field theory that allows the study of numerous dynamic situations but does not adequately incorporate correlations, particularly dynamic correlations, which are essential for understanding strongly out-of-equilibrium systems. This is a challenging topic that has been studied for decades in various fields of physics and chemistry. Progress is steady but slow. The team’s work focuses notably on extending TDDFT using methods inspired by kinetic theories (including stochastic extensions), specifically in terms of density matrices.
This research has led to the open-source release of the QDD code for finite systems, based on TDDFT but incorporating dynamic correlations.
The Quantum Coherence team deals with many aspects related to interference, entanglement and nonlinearity effects in complex quantum systems. It studies in particular the effects of classical and quantum chaos, waves in complex environments, information and quantum computation. It has also developed expertise in the study of complex networks, large databases and signal processing.
The research topics of our group are (see also the Quantware website.) :
- Classical and quantum chaos
- Disordered quantum systems, localization, quantum multifractals
- Quantum information and computation, entanglement
- Random matrix theory
- Quantum simulation with cold atoms
- Physics of complex networks

Theory days
Each year, the Quantum Dynamics team organizes in Toulouse a workshop, the Theory Days, on a specific theoretical issue. The Theory Days workshop aims at stimulating constructive discussions, collaborations, and knowledge exchange among a selected group of theoreticians.
