Suppressed terahertz dynamics of water confined in nanometer gaps
Hyosim Yang, Gangseon Ji, Min Choi +10
Nanoconfined waters have been extensively studied within various systems, demonstrating low permittivity under static conditions; however, their dynamics have been largely unexplor…
Keldysh space control of charge dynamics in a strongly driven Mott insulator
Xinwei Li, Honglie Ning, Omar Mehio +7
The fate of a Mott insulator under strong low frequency optical driving conditions is a fundamental problem in quantum many-body dynamics. Using ultrafast broadband optical spectro…
Nematic response revealed by coherent phonon oscillations in BaFeAs
Min-Cheol Lee, Inho Kwak, Yeongseon Lee +5
We investigate coherent phonon oscillations of BaFeAs using optical pump-probe spectroscopy. Time-resolved optical reflectivity shows periodic modulations due to c…
Evidence of structural evolution in Sr2RhO4 studied by time-resolved optical reflectivity spectroscopy
Min-Cheol Lee, Inho Kwak, Choong H. Kim +7
We investigate ultrafast dynamics from photoinduced reflectivity of Sr2RhO4 by using femtosecond near-infrared pulses. We observe a clear temperature-dependent anomaly in its elect…
Revealing electrically undetectable room temperature surface-mobility of bulky topological insulators by spectroscopic techniques
Bumjoo Lee, Jinsu Kim, Jonghyeon Kim +11
High surface-mobility, which is attributable to topological protection, is a trademark of three-dimensional topological insulators (3DTIs). Exploiting surface-mobility indicates su…
