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…
Nonresonant Raman control of ferroelectric polarization
Jiaojian Shi, Christian Heide, Haowei Xu +15
Important advances have recently been made in the search for materials with complex multi-phase landscapes that host photoinduced metastable collective states with exotic functiona…
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…
