Soft Matter is a term for states of matter that are neither simple liquids nor crystalline solids. Materials in such states are well known from everyday life, and form the basis of living organisms. Characteristic for soft matter are length scales intermediate between atomic and macroscopic scales, thermal fluctuations, and self-assembly. In this lecture, we will consider important soft and bio-matter systems such as polymers, proteins, membranes, and networks of polymers or proteins. The lecture includes simple models for these systems, as well as an introduction into simulation methods such as molecular dynamics.
