The Noncommutative Geometry of the Landau Hamiltonian: Metric Aspects
arXiv:2006.06785 · doi:10.3842/SIGMA.2020.146
Abstract
This work provides a first step towards the construction of a noncommutative geometry for the quantum Hall effect in the continuum. Taking inspiration from the ideas developed by Bellissard during the 80's we build a spectral triple for the -algebra of continuous magnetic operators based on a Dirac operator with compact resolvent. The metric aspects of this spectral triple are studied, and an important piece of Bellissard's theory (the so-called first Connes' formula) is proved.
