Main topics  Research overview 
Continuous photodetection modelThe continuous photodetection model (CPM) describes photon counting processes in cavities. It includes the backreaction of the detector on the field upon each photon detection, allowing for quantum control via feedback schemes. Our group is interested in proposing experimental schemes to verify CPM and studying applications of CPM in cavity QED. Besides, we work out theoretically the form of the Quantum Jump operator, which describes the backreaction of the detector on the field. 

Modelling Quantum JumpsWe work out a microscopic model of singlephoton detectors to determine the quantum jump operator, which describes the field state immediately after a single photon absorption (detection). We also determine the backreaction on the field due to dark counts.


Dynamical Casimir EffectWe study photon creation from vacuum due to the Dynamical (Nonstationary) Casimir effect (DCE). We are interested in proposing experimental schemes to verify DCE, so we work out a model for dissipative losses in nonstationary quantum systems. We also study entanglement dynamics, decoherence and nonclassical state generation during DCE. See recent papers (2005): [1], [2], [3], [4], [5], [6], [7], [8]
