Quantization of edge currents along magnetic interfaces: A Ktheory approach

Tue 24 Nov 2020, 3:30pm4:30pm
Abstract
The purpose of this talk is to explain how to describe the propagation of topological currents along magnetic interfaces (also known as magnetic walls) of a twodimensional material using Ktheory. We initially consider tightbinding magnetic models associated with generic magnetic multiinterfaces and we will describe the Ktheoretical setting in which a bulkinterface duality can be derived. Then, we will focus on the (non trivial) case of the Iwatsuka magnetic field. The exposition is intended to be pedagogical and aimed at a nonspecialist audience.

Solvability of some integrodifferential equations with anomalous diffusion in higher dimensions

Tue 12 Jan 2021, 3:30pm4:30pm
Abstract
The work deals with the studies of the existence of solutions
of an integrodifferential equation in the case of the anomalous diffusion
with the negative Laplace operator in a fractional power in R^d, d=4,5.
The proof of the existence of solutions relies on a fixed point technique.
Solvability conditions for non Fredholm elliptic operators in unbounded
domains are used.
