Giant optical spin-orbit interactions in ferroelectric van der Waals waveguides
Ding Xu, Saeed Rahmanian Koshkaki, Vicente Galicia +14
Optical spin-orbit interactions (SOI) link photonic spin to momentum, offering a route toward on-chip polarization control and beam steering. Nevertheless, achieving sufficient opt…
Tunable Narrowband Terahertz Radiation from van der Waals Ferroelectrics
Chun-Ying Huang, Taketo Handa, Daniel G. Chica +10
The terahertz (THz) spectral range is central to high-speed communication, precision metrology, sensing technologies, and a range of fundamental scientific investigations. Achievin…
Observation of Coherent Ferrons
Jeongheon Choe, Taketo Handa, Chun-Ying Huang +16
Excitation of ordered quantum phases gives rise to collective modes and quasiparticles, as exemplified by spin waves and magnons emerging from magnetic order. Extending this paradi…
Charge Density Wave and Ferromagnetism in Intercalated CrSBr
Margalit L. Feuer, Morgan Thinel, Xiong Huang +25
In materials with one-dimensional electronic bands, electron-electron interactions can produce intriguing quantum phenomena, including spin-charge separation and charge density wav…
A 2D van der Waals Material for Terahertz Emission with Giant Optical Rectification
Taketo Handa, Chun-Ying Huang, Yiliu Li +7
Exfoliation and stacking of two-dimensional (2D) van der Waals (vdW) crystals have created unprecedented opportunities in the discovery of quantum phases. A major obstacle to the a…
Coupling of Electronic Transitions to Ferroelectric Order in a 2D Semiconductor
Chun-Ying Huang, Daniel G. Chica, Zhi-Hao Cui +16
A ferroelectric material often exhibits a soft transvers optical (TO) phonon mode which governs it phase transition. Charge coupling to this ferroelectric soft mode may further med…
