Quasicrystalline oxide interfaces by twisting SrTiO3 membranes
Shivasheesh Varshney, Sooho Choo, Huan Liu +34
Quasicrystals reveal that long-range order can exist without translational periodicity, but deterministic routes for designing strongly bonded quasicrystalline interfaces remain un…
Light-Driven Ultrafast Control of Time-Reversal Symmetry in SrTiO3
In Hyeok Choi, Sergei Urazhdin, Shivasheesh Varshney +3
Light-driven control of material symmetry enables the engineering of phenomena forbidden in equilibrium. Although electromagnetic fields have been used to break time-reversal symme…
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…
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…
Triply degenerate nodal points in RERhGe (RE=Y, La, Lu)
Peng-Jie Guo, Huan-Cheng Yang, Kai Liu +1
As a new type of fermions without counterpart in high energy physics, triply degenerate fermions show exotic physical properties, which are represented by triply degenerate nodal p…
