In this chapter, I introduce the basic concepts and tools useful to study granular media. A tour is offered through some of the many fascinating granular phenomena. These include hydrodynamic instabilities such as granular jets, fingering, spontaneous segregation, thermal-like convection, and the several ratchet-like phenomena where "thermal" fluctuations are somehow rectified. The analogy with active fluids is also discussed.

Abstract
In this chapter, I introduce the basic concepts and tools useful to study granular media. A tour is offered through some of the many fascinating granular phenomena. These include hydrodynamic instabilities such as granular jets, fingering, spontaneous segregation, thermal-like convection, and the several ratchet-like phenomena where "thermal" fluctuations are somehow rectified. The analogy with active fluids is also discussed.File in questo prodotto:
