Events for 30 October 2017

Matt Roberts: Exceptional times of the critical dynamical Erdős-Rényi graph

12:00am, CM221

It is well known that the largest components in the critical Erdős-Rényi
graph have size of order n^{2/3}. We introduce a dynamic Erdős-Rényi
graph by rerandomising each edge at rate 1, and ask whether there exist
times in [0,1] at which the largest component is significantly larger
than n^{2/3}.

Steven Sivek: Contact structures, instantons, and Floer homology

4:00pm, CM219

Instanton homology was developed by Floer in the 1980s as a powerful invariant of 3-manifolds. In recent years, it has had some striking applications in low-dimensional topology which were inspired by newer, more accessible relatives such as Heegaard Floer homology. I will describe some joint work with John Baldwin along these lines, in which we use invariants of contact structures on 3-manifolds to study the fundamental groups of 3-manifolds which bound Stein surfaces, and to prove that a knot invariant called Khovanov homology detects the trefoil.

Vaios Ziogas: Holographic Diffusion

5:00pm, OC218

In this talk I will consider transport of conserved charges in strongly coupled quantum systems with broken translations, using holographic techniques. Such systems are relevant in condensed matter physics in the context of spontaneous symmetry breaking as well as in the context of
momentum relaxation through a lattice. After introducing the relevant concepts, I will give the precise identification of the hydrodynamic modes that diffuse heat and electric charge. As an aside, in the case of explicit breaking I will connect with previous results of DC conductivities from black holes horizons via an Einstein relation for the diffusion constants.
