이번 학기 콜로퀴움은 학교의 권고를 따라, 사회적 거리두기 단계와 연계하여 온라인 혹은 오프라인(온라인 방송 병행)으로 운영될 예정입니다.

세번째 강연에는 성균관대학교 물리학과 황정식 교수님을 모시고 콜로퀴움을 개최하오니, 학과 구성원 여러분의 많은 참여를 부탁 드립니다.

코로나19 확산방지를 위해 다과는 제공하지 않습니다.

5. Abstract: Optical spectroscopy is one of important spectroscopic techniques for condensed matter physics. Condensed matters show their own unique phononic (or lattice vibration modes) and electronic structures, which are caused by collective contributions of constituent atoms. Optical transitions occur by promoting electrons from occupied states below the Fermi level to unoccupied ones above it. Therefore, the information of phononic and electronic structures of the condensed material system are encoded in measured optical spectra. In first part of this talk, I will briefly introduce optical spectroscopy technique and some known analysis methods of measured optical spectra.
Superconductivity is one of most intriguing phenomena in condensed meter physics. In a superconducting state, electron pairs are formed by effectively attractive force created by various microscopic mechanisms and condensed into a macroscopic ground (superconducting) state. Finding out the pairing glue for electrons pairs is the key task for understanding the superconductivity. In the second part of the talk, I will briefly introduce superconductivity and discuss how the glue (spectrum) can be obtained by using optical spectroscopy.
