Quantum materials are the vast varieties of materials where interactions introduce collective behaviors that cannot be inferred from individual electrons or atoms. One manifestation of emergent behaviors is the formation of spontaneous symmetry breaking phases and their collective excitations. In this talk, I will show how we use ultrashort laser pulses to study an interesting symmetry breaking phase, the ferro-rotational phase that is characterized by the ordering of head-to-tail loops of electric dipoles, and probe its dynamics.
