Plasmonic Forces

I am studying the momentum transfer from fast electrons, like those typically used in electron microscopy, to metallic nanoparticles of few nanometers in size, looking for an explanation for the unexpected theoretical result, and later demonstrated experimentally, of repulsion effect between the probe and the target, opening the possibility of using electron beams as a powerful nano-manipulation tool and as a trapping technique for particles or small molecules.

This project involves analytical calculations and high-demanding computing calculations, as well as state of the art experiments. In this topic there are available positions from social service, undergraduate, master to PhD thesis, working either/both theoretical and computing physics.

I am collaborating with a high-level team with very well known physicists in the field of Electron Energy Loss Spectroscopy (EELS) and interaction of Electromagnetic Fields with matter, both theorist and experimentalist: Prof. Pedro M. Echenique, Prof. Allberto Rivacoba, Prof. Archie Howie, Prof. Rubén G. Barrera, Prof. Javier Aizpurua and Prof. Philip E. Batson.

There are several students working currently in this subject: Arturo Santos (PhD thesis), Víctor Miguel Almazán González (PhD thesis), José Angel Castellanos Reyes (Master thesis), Carlos Alberto Maciel Escudero (Master thesis) and Carlos Gael Ortiz Solano (undergraduate thesis). Former students: Arturo Santos Gómez (master thesis).

We have published several papers in highly ranked journals as Nano Letters, Physical Review B, MRS Bulletin and Ultramicroscopy.
