The group for Theoretical Quantum Optics, headed by Prof. John Martin since 2011, is part of the Atomic and Nuclear Physics pole of the University of Liège (Belgium), along with the Coldatom Physics group (Prof. Thierry Bastin) and the Quantum Statistical Physics group (Prof. Peter Schlagheck).
The Atomic and Nuclear Physics pole is part of a larger research unit named CESAM.
Our research activities revolve around quantum optics, cold atom physics, quantum information theory and quantum chaos. More specifically, we are interested in ❯❯ the consequences of the coupling between internal and external degrees of freedom of cold atoms, mainly in the context of open quantum systems, ❯❯ multipartite entanglement (its detection, classification and quantification) and nonclassical correlations, in particular for multiqubit symmetric states and spin states, ❯❯ quantum chaos in BoseEinstein condensates, multifractality of quantum wave functions, models displaying an Anderson delocalizationlocalization transition.
