Spectral Anisotropy in Transition Radiation from Biaxial Media
Sven Ebel, Bibi Mary Francis, Min Seok Jang +4
In anisotropic optical media, the electromagnetic response depends on the orientation of the optical field relative to the material's principal dielectric axes. While this directio…
Unveiling the Spin-Valley Structure of Dipolar Exciton Ladders in R-stacked WSe/WS Moiré Heterobilayers
Byeong Wook Cho, Tatyana V. Ivanova, Zhe Li +4
Localized interlayer excitons in moiré heterobilayers can form dipolar exciton ladders, yet their internal spin-valley structure remains unresolved. Here, we use helicity-resolved…
Twist-Engineered Nonlinearity in Two-Dimensional Crystals for Tailored Quantum Light
Dylan Mcleod, Fabrizio Chiriano, Francesco Graffitti +3
Van der Waals (vdW) materials enable nonlinear-optical engineering with unprecedented resolution: their strong second-order susceptibilities () and twist-tunable interlay…
Photoexcitation of moiré-trapped interlayer excitons via chiral phonons
A. Borel, T. V. Ivanova, J. Cervantes-Villanueva +7
Moiré superlattices in transition-metal dichalcogenide semiconductor heterobilayers enable the quantum confinement of interlayer excitons with large out-of-plane permanent electri…
Roadmap: 2D Materials for Quantum Technologies
Qimin Yan, Tongcang Li, Xingyu Gao +29
Two-dimensional (2D) materials have emerged as a versatile and powerful platform for quantum technologies, offering atomic-scale control, strong quantum confinement, and seamless i…
Highly tunable band structure in ferroelectric R-stacked bilayer WSe
Zhe Li, Prokhor Thor, George Kourmoulakis +6
Transition metal dichalcogenide homobilayers unite two frontiers of quantum materials research: sliding ferroelectricity, arising from rhombohedral (R) stacking, and moiré quantum…
