Condensed matter is found in a variety of phases, the vast majority of which
are characterized in terms of symmetry breaking. For example, magnets
spontaneously break time-reversal and spin-rotation symmetries. A notable
exception was provided by the discovery of the fractional quantum Hall effect
which exhibits new kinds of topological orders not associated with any
symmetry breaking. One of the characterizing features of topological order is
the existence of excitations with exotic properties. These so-called anyonic
excitations might make topologically ordered systems ideal building blocks of
fault-tolerant quantum computers. In this talk, I will start by giving a
general introduction to the concept of topological order and then address some
of the recent developments. In particular, I will introduce theoretical
frameworks that allow us to classify topological phases and discuss dynamical
signatures that are useful to experimentally detect them.
