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.
