###### Title: Models of matter with microstructure

Abstract:

In classical continuum mechanics, a material
medium consists of structureless points. In the early 20th century, the Cosserat brothers proposed a generalization of this simple picture, in which the material body or fluid is formed by particles whose microscopic properties contribute to the macroscopic dynamics of the medium. These more complex continuous mechanical models are known under different names, such as the theories of multipolar, micromorphic, or oriented media. Important particular cases of continua with microstructure is represented by the spinning fluids and bodies, ferromagnetic materials, cracked media, liquid crystals, superfluids,
and granular media. We discuss the Lagrangian theories of material media with microstructure in flat and curved spacetime. The symmetries, conservation laws and the equations of motion are derived for the models of fluids, particles and extended bodies with microstructure. Their possible applications as detectors of the geometrical structure of spacetime are reviewed.
