- 요약The field of topological materials offers an intriguing breakaway from the typical Landau symmetry breaking paradigm of phase transitions. In topologically nontrivial materials, inverted band structure leads to surface states which are topologically protected in the presence of disorder. The interplay between topology and the time-reversal symmetry breaking of magnetism yields exotic physics such as the quantum anomalous Hall effect and the axionic insulator state. Concurrent with the advances in topological materials is the field of 2D magnets and Van der Waals materials which offer physicists the ability to study magnetism in low dimensions with the added benefit of easy exfoliation to create even and odd layered samples and hetero-structures on demand. Pumping these materials with pulsed lasers allows for the direct excitation of a nonequilibrium population of hot electrons, and probing with light is an excellent tool to observe how the charge, lattice, and spin degrees of freedom interact with each other. In this work we will investigate magnetization dynamics and spin-phonon coupling in bulk MnBi2Te4, the first intrinsic magnetic topological insulator.
