Ph.D., University of Michigan Field: Theoretical High Energy Physics My research interests include topics on the foundations of physics and general relativity.

My present research is on the foundations of quantum physics.

I am working on a project titled “Virtual interference pattern”. The virtual interference pattern concept originated in the analysis of the results of an experiment. This concept is needed to preserve the principle of complementarity and momentum conservation.

Virtual interference pattern introduces to optics a concept already present in quantum electrodynamics. In quantum electrodynamics and in general in quantum field theory there are several situations where field predictions stay at the virtual level. For instance, there are particles, such as the Higgs boson, predicted by the fields that contribute to processes but are not normally formed due to a failure to fulfill energy-momentum conservation. Similarly, in my work, I find a situation where the electromagnetic field predicts interference fringes that are not always realized due to failure to meet momentum conservation.

The concept of virtual interference pattern hints a disconnection between particle aspect and wave aspect for the photon. Experimental evidence suggests that under certain circumstances particle aspect and wave aspect develop independently. In spite of the interdependence between wave and particle, any hint of independent development of wave and particle implies that they are separate objects. Thus, I believe that my work could contribute in the research of the nature of wave and particle aspects of the photon. Better understanding the nature of the photon is, in our opinion, a subject of great general interest.

My work includes diffraction calculations using quantum electrodynamics techniques. Historically, diffraction has been calculated using classical wave techniques; however, it is in principle important to learn how to calculate diffraction using QED. Ideally, QED should provide a more accurate description of diffraction
