报告题目：New Functionalities in Low-dimensional Magnetic Materials

报告摘要：Using density functional approach and model simulations, physical properties of many systems can be reliably predicted and explained. In this talk, I will discuss examples of our recent theoretical studies of low-dimensional magnetic materials, from quantum spin states of magnetic molecules to the magnetic topological materials. More explicitly, I will discuss the effect of spin-vibration coupling on spin decoherence in small systems such as single magnetic molecule or atom. For topological materials, I will focus on the manipulation of corner states of high order topological insulators with magnetic and electric fields. Some results will be discussed along with experimental data from collaborators.
