Abstract: Magnetism has a long history, dating back to the use of compasses in ancient voyages. However, our modern understanding of magnetism began to take shape with the development of quantum mechanics. To elucidate and manipulate the magnetic properties of quantum materials, a deep dive into the microscopic Hamiltonians specific to each materials is essential. While the Heisenberg model is widely recognized in the magnetism community, recent advancements have revealed that various forms of spin interactions can emerge through the interplay of spin-orbit coupling and electron interactions. In this talk, I will illustrate a selection of such models in different magnetic materials and discuss their significance in the context of quantum spin liquids featuring fractionalized excitations.
