I am in Germany... but why?
My work
I am a PhD student working in the GSI theory group. I work in Nuclear Structure with a model called Fermionic Molecular Dynamics.
Catching up
After the first year here, I have written a work like a spanish "tesina" or german "diplomarbeit", needed to make the complete equivalence of studies:

I summarized this work in a short talk given in Tuebingen during the spring DPG meeting in the area of Nuclei and Hadrons:

My thesis
Oriented by Prof. Dr. H. Feldmeier, I got immersed in the calculation of resonances in the many-body model of the group. The idea was to develop a method in order to define the relative distance between the two fragments in the fully antisymmetrized many-body problem, and use this to formulate the appropriate boundary conditions for a resonant state. These conditions were then nicely implemented in the many-body Schroedinger equation in such a way that we obtained a modified eigenvalue problem (modified matrix elements) including the boundary conditions. After a while, I extended the method to obtain also scattering states for elastic collisions.
The three years and a half yielded a PhD thesis in which I developed these ideas in a schematic model, and finally applied them to a many-body system with a realistic interaction. I tested the validity of the method and then obtained the first results in FMD for the different asymptotic behaviours. You can take a look!

I defended my PhD in the TU-Darmstadt. The first part of the defense is a 20 min. talk:

During my holiday in Colombia, I took the chance to give a seminar in the National University of Bogota:

The credit for the nice 3D intrinsic one-body densities and energy levels goes to Thomas Neff, from whom I took them borrowed, as well as a whole slide. No need to remake when there is nothing to improve!
And how it comes I am here?
In the year 2001 I got a grant to come for the Summer Student Program in the GSI. I spent two great months, learning a lot about other countries and meeting nice people. In the academic field, I wrote my first pseudo-scientific report:

I even gave a talk about it, my friends obviously liked it:
