Biography
Patricio Robles has a long professional and academic career as a physics teacher and researcher, as well as an electrical engineer. Despite being retired, he continues developing research in theoretical physics and teaching courses on electrical projects at Pontifical Catholic University of Valparaíso, Chile. He also works as a consulting engineer in electrical studies related to the analysis of faults in electrical systems and protection schemes. He has published his research concerned with topics about electromagnetic fields and quantum physics in international journals and book chapters. His more recent publications are related to bounded pairs of electrons, massless Dirac fermions, and photon propagation through dispersive media. During last five years, he has collaborated with international journals of physics and electrical engineering as a referee, reviewing articles submitted for publication in journals such as the European Journal of Physics and Nanotechnology Journal.
