Description

Soft matter is an important sub-class of condensed matter. It includes a wide range of intriguing substances like colloids, polymers, liquid crystal or foams and emulsions. We experience the physical properties of such systems every day : milk, paint, cosmetics, gels or shaving foams, just to mention few of them.

Soft matter systems typically consist of a large number of small elements whose interaction energies are comparable to thermal energy. At this weak energy scale, entropy is often an important key player in controlling the materials behaviour in contrast to traditional hard matter. As a result, Soft Matter systems display an extraordinary rich and, sometimes, counter-intuitive behaviour even at room temperature. The same material may behave like a fluid or like a solid, depending on the experimental conditions. Materials may harden with increasing temperature or under mechanical solicitation and substances may become more soluble upon decreasing the temperature. The interactions with light can be highly non-trivial and photonic properties of soft matter are of great interest.

Understanding the governing physical principles of soft matter is a challenge that requires a joint theoretical, computational and experimental effort. In combining efficiently these three dimensions, Soft Matter research has advanced significantly over the last 30 years and provides now a very important and illustrative playground for the physicist who needs to relate the physics of the material on a microscopic level to its macroscopic behaviour. On the other hand, Soft Matter can be the ideal test ground for statistical mechanics concepts. Moreover, few physical disciplines have such a direct link with industrial applications and also with the living world at the ever-growing interface between physics and biology.

Combining theory, experiments and computer simulations - and using a wide range of example systems - this course aims to introduce some of the key concepts of Soft Matter Science. In particular, the concept of coarse-graining will be introduced, opening the route to the reduction of the degrees of freedom of soft matter system to make it theoretically amenable. We will lay the basis of the theory behind the treatment of the static and dynamics properties of some soft matter systems. The connection to real systems will be always stressed and some of the most striking properties of Soft Matter systems will be illustrated by simple hands-on experiments. Beyond learning about the well-understood and well–accepted part of Soft Matter Science, the students will be in touch with partially solved or open scientific problems through a « Journal club » at the end of each course block, in which some of the most important scientific articles of the field will be discussed by the students.
