Abstract: 

Quantum materials lying at the frontier of condensed matter research call for access to increasingly low frequencies in the electromagnetic spectrum. In particular, the terahertz region is a rich arena for probing exotic quasiparticles associated with novel quantum phenomena. Ultrafast femtosecond lasers developed in the late 1990s brought an unexpected opportunity to implement terahertz time-domain spectroscopy (THz-TDS). Here, we introduce the standard method of THz-TDS and illustrate this technique by presenting several case studies in which the distinct advantages of THz-TDS were utilized to obtain key information on representative quantum materials such as topological insulators, superconductors, and low-dimensional van der Waals magnets.
