물리학과 초세대 협업 연구실에서 주관하는 Quantum- & Nano-Photonics Sebinar 시리즈 공지를 안내드립니다.

양자 및 나노광학 분야의 해외 연구자를 초청하여 최신 연구 동향을 파악하고 상호 교류하기 위해 마련된 본 세미나 시리즈의 다음 강연을 소개해드립니다.
관심있는 분들의 많은 참석 부탁드립니다.

이번 연사는 물리학과 이상민 교수님께서 초청하신 Ulrich Hoefer 교수님이며, 시분해 분광학, photo-emission spectroscopy 분야의 대가입니다.
소개와 세미나 내용은 다음과 같습니다.

1. 연사: Prof. Ulrich Höfer (Department of Physics, Philipps University of Marburg, Germany)
              https://scholar.google.com/citations?user=50l_zaUAAAAJ&hl=de

2. 발표제목: Time-resolved photoemission: From bandstructure to orbital movies

3. 일시: 2024년 11월 21일 목요일 오후 4시

4. 장소: 자연과학동 (E6-2) 물리학과 #1323

5. 초록:
Time-resolved photoemission combines femtosecond pump-probe techniques with angle-resolved photoelectron spectroscopy (ARPES). Recent developments enable the method to track electron motion in two-dimensional momentum space on ultrafast time scales, in the case of THz and MIR pump radiation with subcycle resolution. In this talk, I will briefly introduce the state-of-the-art of the method and discuss a couple of examples from our recent work. These include bandstructure movies of the intraband acceleration of electrons in topologically protected Dirac surface states, of the birth and collapse of Floquet-Bloch states, and of the formation of momentum-forbidden and spin-forbidden dark excitons in TMDC monolayers. Finally, I will outline the perspectives of photoemission orbital tomography to take slow-motion movies of molecular orbitals while they are driven by lightwaves.
