Title |
The Nobel prize in Physics 2016: Topological phases of matter |
|
Abstract |
Last year's Nobel prize in physics was awarded to Kosterlitz, Thouless and Haldane for their
pioneering work on topological phase transitions and topological phases of matter. In this talk, I
will present some of their work, focusing in particular on the novel understanding of band
theory that emerged thanks to these researchers and as a consequence of the experimental
discovery of the quantum Hall effect. I will also try to clearly distinguish between different uses
of topology in condensed matter physics and to outline what is truly topological from what is
merely geometrical (but not least interesting). The main examples that I will discuss are the
integer quantum Hall effect and the anomalous quantum Hall effect (Chern insulator). |
