Learning unit contents

This lecture provides an introduction to the fundamental concepts of soft matter, a field at the interface of statistical physics, thermodynamics, and fluid mechanics. It focuses on the physical mechanisms governing systems whose structure and dynamics result from a subtle balance between interactions, thermal fluctuations, interfacial forces, and external driving.

The main topics covered include particle interactions; Brownian motion, diffusion, and sedimentation; interfaces, surface tension, capillarity, and wetting; foams and emulsions; suspensions, colloids, gels, and pastes; as well as their rheological behavior. Particular attention is paid to length, time, and energy scales, and to dimensionless numbers used to identify the dominant physical mechanisms. The concepts are illustrated through experimental systems and examples drawn from everyday situations.

Learning outcomes of the learning unit

The main objective of the lecture is to provide students with the concepts and tools needed to understand the physical properties of soft matter and to relate behaviors observed at the macroscopic scale to mechanisms operating at mesoscopic and microscopic scales.

By the end of the course, students will be able to:

  • identify the main classes of soft materials and their physical characteristics;
  • determine the relevant length, time, force, and energy scales for a given system;
  • compare different physical mechanisms using order-of-magnitude estimates and dimensionless numbers;
  • understand phenomena related to interfaces, capillarity, wetting, and the stability of dispersed systems;
  • describe the physical mechanisms governing colloids, suspensions, emulsions, foams, gels, and pastes;
  • characterize the main rheological behaviors of soft materials.
