Dr. Gaspar Orriols has done experimental and theoretical research on Laser Spectroscopy and Quantum Optics, Nonlinear Optics and Nonlinear Dynamics since 1975, first at the Istituto di Fisica Atomica e Molecolare del CNR (Pisa) and then at the Physics Department of the UAB. His main findings include (the participation in) the discovery and explanation of the energy pooling phenomenon in collisions between excited atoms and of the coherent population trapping, which has now become a classical issue in quantum optics. He built up a research group at the UAB devoted to Nonlinear Systems with findings on optical bistability (cavity optimization by separating functions in thermo-optical bistability), nonlinear dynamics (amplitude death effect in coupled oscillators and full instability behavior in the Generalized Landau scenario), nonlinear optics (second harmonic generation in poled glasses) and multilayer optics (patent on a technique for best visualization of blood vessels).
His current research goals include the analysis of potential connections of the Generalized Landau scenario with the complex oscillatory behaviors of fluid turbulence and brain dynamics, as well as with the structural evolution of systems at both macro and microscopic scales.
