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…
Dynamically suppressed lattice rotations in SrTiO as a basis for photo-induced ferroelectricity
Huaiyu Hugo Wang, Michael Fechner, Giovanni De Vecchi +22
Photo-induced ferroelectricity in the quantum paraelectric SrTiO involves the dynamical interplay between a coherently driven Ti-O stretching vibration and multiple structural…
A textured polar phase in strained SrTiO3
Huaiyu Hugo Wang, Ernesto Flores, Jade Stanton +11
Quantum materials can harbour hidden phases whose microscopic structures differ from conventional ordered states while reproducing their macroscopic signatures, making them easy to…
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…
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…
