Steve Simon, Tutorial Fellow of Somerville College, will speak at the colloquium "Topologically Ordered Matter and Why You Should be Interested" on Monday, July 2nd, from 14:30 till 15:30 at Institut de Physique Théorique at St-Aubin, on the topic of condensed matter theory.

Pr Steve SimonThe colloquium is part of the thematic programs of Psi2, a program from Université Paris-Saclay that funds and organizes long-term visits of high-level scientists. The programs are selected by the Psi2 scientific council and are devoted to the following topics: Astrophysics and Cosmology, Physics and its interfaces.


In two dimensional topological phases of matter, processes depend on gross topology rather than detailed geometry. Thinking in 2+1 dimensions, particle world lines can be interpreted as knots or links, and the amplitude for certain processes becomes a topological invariant of that link. While sounding rather exotic, we believe that such phases of matter not only exist, but have actually been observed in quantum Hall experiments, and could provide a uniquely practical route to building a quantum computer. Possibilities have also been proposed for creating similar physics in systems ranging from superfluid helium to strontium ruthenate to semiconductor-superconductor junctions to quantum wires to spin systems to graphene to cold atoms.
