Selected Problems of Two-Dimensional Magnetism

Explore key aspects of two-dimensional magnetism in this 35-minute conference talk delivered by Mikhail Katsnelson at the Workshop on "Spin-Orbit Entangled Quantum Magnetism" held at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI). Delve into four crucial topics: the impact of spin fluctuations and long-range dipole-dipole interactions on 2D magnetism, the potential role of magnetic polarons in materials like CrX3, the unique characteristics of exciton spectra and magnetooptical properties in CrX3 and CrSBr, and the hybridization of plasmons and magnons in 2D ferromagnets. Gain insights into how plasmon measurements can be utilized to probe the spin-wave spectrum of 2D materials.
