Discovery of Light-induced Metastable Martensitic Anomaly Controlled by Single-Cycle Terahertz Pulses

X. Yang, B. Song, C. Vaswani +9

We report on an ultrafast photoinduced phase transition with a strikingly long-lived Martensitic anomaly driven by above-threshold single-cycle terahertz (THz) pulses in Nb $_{3}$ Sn.…

Ultrafast Control of Excitonic Rashba Fine Structure by Phonon Coherences in a Metal Halide Perovskite CH $_{3}$ NH $_{3}$ PbI $_{3}$

Z. Liu, C. Vaswani, X. Yang +14

We discover hidden Rashba fine structure in CH $_{3}$ NH $_{3}$ PbI $_{3}$ and demonstrate its quantum control by vibrational coherence through symmetry-selective vibronic (electron-phonon) c…
