Unveiling High-Energy Ultrafast Responses Driven by Fermi-Level Gap Opening in Charge-Density Waves
Qiong Wu, Tianchen Hu, Junhan Huang +8
Ultrafast pump-probe spectroscopy is indispensable for investigating interactions, collective excitations, and nonequilibrium dynamics in superconductors and correlated electron sy…
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…
Efficient high-harmonic generation in van der Waals ferroelectric NbOI crystals
Tianchen Hu, Feng Li, Junhan Huang +8
Layered NbOX (), a member of the van der Waals ferroelectric family, exhibits intrinsic ferroelectricity and pronounced nonlinear optical responses, mak…
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…
Ultrafast Orbital-Selective Photodoping Melts Charge Order in Overdoped Bi-based Cuprates
Xinyi Jiang, Qizhi Li, Qingzheng Qiu +10
High-temperature superconductivity in cuprates remains one of the enduring puzzles of condensed matter physics, with charge order (CO) playing a central yet elusive role, particula…
