Physics of Granular Systems Reseach Gorup

The Physics of Granular Systems Research Group (GFSG, Spanish acronym) develops research and innovation in the area of granular matter.

Granular systems are those formed by a large number of macroscopic particles (the grains). Examples of these are bulk solids such as gravel and sand; many food stuff (like sugar, salt, coffe, etc.); agricultural commodities (cereals, beans, seeds, etc); industrial products (pellets, pills, screws, nuts, etc.); as well as different astrophysical systems where grains can have the scale of a planet. 

These systems present some peculiar features when compared to more traditional systems where the basic constituents are atoms or molecules. In a granular system each grain interacts with other through dissipative forces, loosing energy at each contact or collision. This gives rise to a variety of interesting physical phenomena, many of which remain still unexplained. Many of the basic postulates used in statistical physics and thermodynamics are invalid for granular materials. Therefore, there is a need for the development of new theoretical frameworks to understand their behavior.  

The GFSG utilizes ad hoc experiments, theoretical models and computer simulations to study a variety of phenomena related with granular systems.
