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 NbSn.…
Ultrafast Control of Excitonic Rashba Fine Structure by Phonon Coherences in a Metal Halide Perovskite CHNHPbI
Z. Liu, C. Vaswani, X. Yang +14
We discover hidden Rashba fine structure in CHNHPbI and demonstrate its quantum control by vibrational coherence through symmetry-selective vibronic (electron-phonon) c…
Competing Orders and Ultrafast Energy Transfer at the Quantum Limit in a NbSn Superconductor Probed by Terahertz Electrodynamics
X. Yang, X. Zhao, C. Vaswani +10
We report the low-energy electrodynamics of a moderately clean A15 superconductor (SC) following ultrafast excitation to understand and manipulate terahertz (THz) quasi--particle (…
The mechanical relaxation study of polycrystalline MgCNi3
Y. X. Yao, X. N. Ying, Y. N. Huang +6
The mechanical relaxation spectra of a superconducting and a non-superconducting MgCNi3 samples were measured from liquid nitrogen temperature to room temperature at frequency of k…
