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…
Ultrafast signatures of spin and orbital order in antiferromagnetic -SrCrO
Min-Cheol Lee, Connor Occhialini, Jiarui Li +6
We used femtosecond optical spectroscopy to study ultrafast spin and orbital ordering dynamics in the antiferromagnetic Mott insulator -SrCrO. This chromate system posse…
Ultrafast dynamics in the Lifshitz-type 5 pyrochlore antiferromagnet CdOsO
Inho Kwak, Min-Cheol Lee, Byung Cheol Park +7
We investigate the ultrafast dynamics of CdOsO, a prototype material showing a Lifshitz-type transition as a function of temperature. In the paramagnetic metallic state…
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…
Abnormal flip in coherent phonon oscillations of CaRuO
Min-Cheol Lee, Choong H. Kim, Inho Kwak +9
We employ an optical pump-probe technique to study coherent phonon oscillations in CaRuO. We find that oscillation-amplitude of an symmetric phonon mode is strongly s…
