Abstract

In recent years there has been a growth in interest in materials in which quantum effects manifest over a wide range of energies and size scales. Such materials are called quantum materials and include superconductors, graphene, topological insulators, Weyl semimetals, spin quantum liquids, and spin ices. Many of the properties of these systems derive from their low dimensionality, in particular from the confinement of electrons in two-dimensional sheets. In this project, we plan to study the optical response of this type of systems using the rotation of the polarization of waves transmitted by these materials in Faraday rotation measurements using radiation in the terahertz region. Specifically, we will focus the research on the quantization of the optical response in multilayered quantum materials.
