Probing mesoscopic nonlocal screening in van der Waals heterostructures with polaritons
Xuezhi Ma, Zhipeng Li, Ruihuan Duan +17
Predictive optical modelling of van der Waals (vdW) heterostructures is critical for meta-optics, near-field photonics and quantum technologies. At their buried interfaces, charge…
Electric-field Control of Giant Ferronics
Baolong Zhang, Ruihuan Duan, Sobhan Subhra Mishra +8
Ferrons are quantum excitations of electric polarization in ferroelectrics and electric analogues of magnons but have lacked direct experimental verification at room temperature. W…
Optical Switching of Moiré Chern Ferromagnet
Xiangbin Cai, Haiyang Pan, Yuzhu Wang +12
Optical manipulation of quantum matter offers a non-contact, high-precision and fast control. Fractional Chern ferromagnet states in moiré superlattices are promising for topologi…
Strain Induced Robust Skyrmion lattice at Room Temperature in van der Waals Ferromagnet
Xinyi Zhou, Iftikhar Ahmed Malik, Ruihuan Duan +14
Manipulating topological magnetic orders of two-dimensional (2D) magnets by strain, once achieved, offers enormous potential for future low-power flexible spintronic applications.…
Boosting classical and quantum nonlinear processes in ultrathin van der Waals materials
Xiaodan Lyu, Leevi Kallioniemi, Hongbing Cai +11
Understanding and controlling nonlinear processes is crucial for engineering light-matter interaction and generating non-classical light. A significant challenge in ultra-thin nonl…
Fundamental scaling laws of water window X-rays from free electron-driven van der Waals structures
Nikhil Pramanik, Sunchao Huang, Ruihuan Duan +5
Water-window X-rays are crucial in medical and biological applications, enabling natural contrast imaging of biological cells in their near-native states without external staining.…
