Coherent Transfer of Lattice Entropy via Extreme Nonlinear Phononics in Metal Halide Perovskites
Z. Liu, Y. Shi, T. Jiang +8
Entropy transfer in metal halide perovskites, characterized by significant lattice anharmonicity and low stiffness, underlies the remarkable properties observed in their optoelectr…

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…
