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 field-induced metastable magnetization near criticality in FePS3
Batyr Ilyas, Tianchuang Luo, Alexander von Hoegen +8
Controlling the functional properties of quantum materials with light has emerged as a frontier of condensed-matter physics, leading to the discovery of various light-induced phase…
Discovery of magnon self-interaction in a strongly driven antiferromagnet
David Rohrbach, Zhuquan Zhang, Takayuki Kurihara +1
Nonlinear dynamics govern a wide array of natural phenomena and are essential for understanding nonequilibrium behaviors in condensed matter systems. In magnetically ordered materi…
Nanoscale Ultrafast Lattice Modulation with Hard X-ray Free Electron Laser
Haoyuan Li, Nan Wang, Leon Zhang +24
Understanding and controlling microscopic dynamics across spatial and temporal scales has driven major progress in science and technology over the past several decades. While ultra…
Electromagnon signatures of a metastable multiferroic state
Blake S. Dastrup, Zhuquan Zhang, Peter R. Miedaner +6
Magnetoelectric multiferroic materials, particularly type-II multiferroics where ferroelectric polarizations arise from magnetic order, offer significant potential for the simultan…
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…
Observation of polarization density waves in SrTiO3
Gal Orenstein, Viktor Krapivin, Yijing Huang +23
The nature of the "failed" ferroelectric transition in SrTiO3 has been a long-standing puzzle in condensed matter physics. A compelling explanation is the competition between ferro…
Optical-pump terahertz-probe spectroscopy in high magnetic fields with kHz single-shot detection
Blake S. Dastrup, Peter R. Miedaner, Zhuquan Zhang +1
We demonstrate optical pump/THz probe (OPTP) spectroscopy with a variable external magnetic field (0-9 T) in which the time-dependent THz signal is measured by echelon-based single…
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…
Terahertz Field-Induced Reemergence of Quenched Photoluminescence in Quantum Dots
