Anyons are particles that are neither bosons nor fermions. They are fundamental building blocks for realizing topological quantum computers, which promise a fault-tolerant means of performing quantum computation. In this talk, I will explain what anyons are and why the quasiparticles in quantum Hall liquids are expected to be anyons. Finally, I will describe recent experiments that have verified these expectations, more than 40 years after the fundamental theoretical work by Leinaas and Myrheim. Additionally, since the colloquium coincides with the week of the Nobel Prizes, I will briefly introduce the work of the Nobel Committee in Physics.
Thors Hans Hansson
1950 born in Sweden
1979 PhD from the University of Göteborg, following research at Rutherford Laboratory
1979-1984 Postdoc positions at Nordita in Copenhagen, MIT and CERN
1984-1988 Assistant professor at Stony Brook University, New York
1988-present First associate and later full professor at Stockholm University
2014-2022 Member of the Nobel committee for Physics
2016-2018 Director of Nordita, the Nordic Institute for Theoretical Physics, in Stockholm
Until the mid 90 ́s Thors Hans Hansson worked on the Quantum Chromo Dynamics, the theory of the strong force, and particularly on models for the hadron spectrum and the high temperature plasma phase. Since the mid 90 ́s he worked on the theory of strongly correlated electron systems, in particular Chern-Simons theory and conformal field theory approaches to Quantum Hall liquids and on field theories for topological superconductors and their geometric response.
