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…
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…
Strong spin-phonon coupling unveiled by coherent phonon oscillations in Ca2RuO4
Min-Cheol Lee, Choong H. Kim, Inho Kwak +8
We utilize near-infrared femtosecond pulses to investigate coherent phonon oscillations of Ca2RuO4. The coherent Ag phonon mode of the lowest frequency changes abruptly not only it…
Charge-spin correlation in van der Waals antiferromagenet NiPS3
So Yeun Kim, Tae Yun Kim, Luke J. Sandilands +13
Strong charge-spin coupling is found in a layered transition-metal trichalcogenide NiPS3, a van derWaals antiferromagnet, from our study of the electronic structure using several e…
