Ultrafast non-thermal suppression of ferroelectricity by carrier screening in LiNbO3
Man Tou Wong, Zhuquan Zhang, Zi-Jie Liu +1
Ferroelectric materials are key to energy-efficient electronics, memory, and optical applications. While charge carriers typically screen and suppress ferroelectricity, their role…
Terahertz stimulated parametric downconversion of a magnon mode in an antiferromagnet
Zhuquan Zhang, Yu-Che Chien, Man Tou Wong +6
In condensed matter systems, interactions between collective modes offer avenues for nonlinear coherent manipulation of coupled excitations and quantum phases. Antiferromagnets, wi…
Keldysh tuning of photoluminescence in a lead halide perovskite crystal
Zhuquan Zhang, Honglie Ning, Zi-Jie Liu +5
In 1964, Keldysh laid the groundwork for strong-field physics in atomic, molecular, and solid-state systems by delineating a ubiquitous transition from multiphoton absorption to qu…
Discovery of enhanced lattice dynamics in a single-layered hybrid perovskite
Zhuquan Zhang, Jiahao Zhang, Zi-Jie Liu +9
Layered hybrid perovskites have attracted much attention in recent years due to their emergent physical properties and exceptional functional performances, but the coexistence of l…
Terahertz field-induced nonlinear coupling of two magnon modes in an antiferromagnet
Zhuquan Zhang, Frank Y. Gao, Jonathan B. Curtis +9
Magnons are quantized collective spin-wave excitations in magnetically ordered materials. Revealing their interactions among these collective modes is crucial for the understanding…
Terahertz field-driven magnon upconversion in an antiferromagnet
Zhuquan Zhang, Frank Y. Gao, Yu-Che Chien +10
Tailored light excitation and nonlinear control of lattice vibrations have emerged as powerful strategies to manipulate the properties of quantum materials out of equilibrium. Gene…
Snapshots of a light-induced metastable hidden phase driven by the collapse of charge order
Frank Y. Gao, Zhuquan Zhang, Zhiyuan Sun +6
Nonequilibrium hidden states, both transient and long-lived, provide a unique window into thermally inaccessible regimes of strong coupling between microscopic degrees of freedom i…
