DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SGFM/17/">Qu
 antization of edge currents along magnetic interfaces: A K-theory approach
 </a>\nby Giuseppe De Nittis (Pontificia Universidad Católica de Chile) as
  part of Seminario de Geometría y Física - Matemática UCN-USP\n\n\nAbst
 ract\nThe purpose of this talk is to explain how to describe the propagati
 on of topological currents along magnetic interfaces (also known as magnet
 ic walls) of a two-dimensional material using K-theory. We initially consi
 der tight-binding magnetic models associated with generic magnetic multi-i
 nterfaces and we will describe the K-theoretical setting in which a bulk-i
 nterface duality can be derived. Then\,  we will focus on the (nontrivial)
  case of the Iwatsuka magnetic field. The exposition is intended to be ped
 agogical and aimed at a non-specialist audience.\n\nWork in collaboration 
 with: Esteban Gutiérrez\n
