Condensed matter physics is a branch of physics which studies the properties of collections of particles using quantum mechanics, statistical mechanics and electromagnetism. It is one of the largest areas of research in physics which helps us to understand the properties of matters that we encounter in our daily life such as metals, insulators, semiconductors, liquids, magnets and more exotic matters such as superconductors.
The theory groups are interested in studying novel states of matter at low temperatures when quantum mechanical effects play important roles. Using both numerical and analytical techniques, we study the properties of materials when electron-electron interactions are important. Many novel materials including topological insulators, Dirac semimetals, Weyl semimetals and two-dimensional materials have been predicted and studied by our faculty. We also study novel superconductors such as topological superconductors and other unconventional superconductors.
The experimental condensed matter physics is the biggest research field in the department. It composes of more than ten professors with various experimental techniques. One of the main focus on the condensed matter experimental group is on the study of the properties of quantum materials. The experimental condensed matter physics research of the department ranges from nano materials, semiconductors, superconductors, surface physics, etc., with materials from carbon nanotubes, two dimensional materials such as graphene and transition metal dichalcogenides, topological insulators, iron based and other unconventional superconductors, to single molecules and artifical structures on metal surfaces, etc.
