Temperature-driven sodium-ion dynamical-to-static crossover in the zig-zag ordered phase of NaCoO
Shangfei Wu, Hengxin Tan, Dong Wu +7
The study combines polarization‑resolved Raman spectroscopy and first‑principles calculations to reveal a temperature‑driven dynamical‑to‑static crossover of sodium ions in Na0.5Co…
Ultrafast giant enhancement of second harmonic generation in a strongly correlated cobaltite
Yuchen Cui, Qiaomei Liu, Qiong Wu +15
In quantum materials, nonlinear optical responses are highly sensitive to electronic structure and many-body interactions. Probing and manipulating such nonlinear processes is a co…
Coherent seeding and control of dynamical ferroelectricity by phonon anharmonicity
Junhan Huang, Yongkang Ju, Xinbo Wang +12
Optical control of quantum materials has progressed along two separate directions: creating non-equilibrium states inaccessible at equilibrium, and coherently controlling ultrafast…
Phonon anomalies within the polar charge density wave phase of the structurally chiral superconductor MoAlC
Shangfei Wu, Xianghan Xu, Fei-Ting Huang +3
We employ polarization-resolved Raman spectroscopy to study the lattice dynamics of the polar charge density wave phase of the superconductor MoAlC with structural chiralit…
Nematicity in iron pnictides: phase competition and emergent symmetry
Yiming Wang, Changle Liu, Shan Wu +3
The phase diagram of iron-based superconductors contains a host of electronic orders, which are intimately connected with their superconductivity. Here we analyze the fluctuations…
Lattice dynamics and spin-phonon coupling in the kagome spin ice HoAgGe
Shangfei Wu, Lingxiao Zhao, Wei Song +5
We employ polarization-resolved Raman spectroscopy and first-principles phonon calculations to study the lattice dynamics and spin-phonon coupling in the kagome spin ice compound H…
