The study of solids that lead to the field of condensed matter physics began around 1850, when researchers tried to understand the properties of steel or light emitting filaments in light bulbs. Many experimental observations contradicted each other. Within 70 years theorists solved many fundamental problems and in 1921 the German physicist Max Born published a unified theory of crystals. A new branch of physics, condensed matter physics, was born. The 20th century has seen many discoveries in condensed matter physics, that shaped our society. For a student the challenge is to understand the step from atomic physics to sets with an essentially infinite number of atoms. It is a testament to the beauty of solid state physics that we can handle these systems using simple models.

When you wonder, why electronic devices are getting more and more powerful, you see condensed matter research at work. It is an important branch for anyone planning to stay in physics.

The lecturer has written a highly recommended manuscript on the subject. Other materials on selected topics are available from my predecessors, which I've linked to below.

>> Steve Simon's notes.
>> Tom Ouldridge's notes on scattering, phonons and band theory.
>> Tomi Johnson holes.
The link to the course reading list is given below. Good introductions to the subject are

  • Kittel
  • Hook and Hall
  • Ashcroft and Mermin (advanced)

Examination material

Your grade will be massively improved by working through past exam papers. Look at B2 exams before 2011 along with A4/B3 exams before 2004/2005 and ignore questions on photonics, device physics, superconductivity, and symmetries.
