Fernando Javier Gómez Ruiz

Postdoctoral Researcher (Avaqus)

I completed my MSc and PhD in Physics at University of Los Andes – Bogotá (Colombia) in 2013 and 2019 respectively. After that, I moved to Donostia International Physics Center (Spain) to work on the quantum dynamics of strongly-correlated quantum systems in out-of-equilibrium states. I earned a Bachelors degree in Physics at National Pedagogical University – Bogotá (Colombia) in 2007.

Scientific Interests

My passion is theoretical quantum physics. Specifically, my research interests are in the scientific boundary between condensed matter physics, statistical mechanics and quantum thermodynamics, quantum information science, and quantum science and technology.
