Module aims

The module aims to

  • Introduce students to the major notions and modern applications of statistical mechanics, modelling of the structure and dynamics of biological and soft materials

  • Demonstrate a variety of mathematical techniques, from stochastic to continuous, required to describe the behaviour of materials at widely separated scales

  • Teach students to read, analyse and discuss current scientific literature in the field of soft matter and biological materials

Module learning outcomes

By the end of this module students should

(Academic)

  • Be able to describe a wide variety of phenomena in soft and biological matter using the unifying mathematical language of statistical mechanics

  • Solve problems usingcalculus of variations

  • Have gained experience of working with recently published papers in the field of soft matter and be able to succinctly summarise their results.

(Graduate)

  • Develop problem-solving skills and abilities to treat problems using a set of different but complementary approaches

  • Ability to read and analyse interdisciplinary literature

Module content

The following topics will be covered:

  • Soft matter and biological materials as subjects of statistical mechanics (SM).

  • Mechanical equilibrium as energy minimisation problem. Protein buckling as a bifurcation.

  • Introduction to fundamentals of SM. Temperature and probability.

  • Ligand-receptor binding as a statistical mechanical problem.

  • Entropy. The principle of free energy minimisation. Thermodynamic and entropic forces.

  • Canonical formalism of SM and examples of biological systems: optical trap, mechanosensitive ion channel, and phosphorylation of proteins.

  • One-dimensional matter: basic models for protein structure. Random walk and the entropic origin of elasticity.

  • Two-dimensional matter: structure and energetics of bubbles, drops and cell membranes. Surface tension and wetting phenomena.

  • Mixing cocktails: phase transitions. The mean field theory.

  • Topics in nonequilibrium and active matter

In addition to lectures, the students will work with recently published papers and will learn to succinctly summarise and present their results.
