Infrared spectroscopy of quantum materials

초록

Infrared spectroscopy is a powerful and versatile experimental technique for studying the electronic response of condensed matter. Infrared spectroscopy measurements in a broad energy region provide invaluable insights on the electronic excitations and collective modes in condensed matter and thus play pivotal roles in establishing current understandings of various classes of condensed matter. Here we discuss the usefulness and importance of infrared spectroscopy to study the physics of quantum materials, which were formerly known as strongly correlated materials. We will describe the basic principles and experimental methods of infrared spectroscopy and discuss how infrared spectroscopy can be utilized to extract quantitative information on the charge dynamics and electronic band structures of quantum materials.
