Hyperbolic-enhanced Raman scattering in van der Waals MoOCl2: from Fano resonances to picomolar detection
Anton Minnekhanov, Gleb Tikhonowski, Georgy Ermolaev +13
Natural van der Waals (vdW) crystals with hyperbolic dispersion challenge artificial metamaterials but remain confined to the mid-infrared. The emergence of MoOCl2, a quasi-one-dim…

Giant optical anisotropy and visible-frequency epsilon-near-zero in hyperbolic van der Waals MoOCl2
Georgy Ermolaev, Adilet Toksumakov, Aleksandr Slavich +14
The realization of extreme optical anisotropy is foundational to nanoscale light manipulation. Van der Waals (vdW) crystal MoOCl2 has emerged as a promising candidate for this ques…

Contact Lens with Moiré patterns for High-Precision Eye Tracking
I. M. Fradkin, R. V. Kirtaev, M. S. Mironov +9
Eye tracking is a key technology for human-computer interaction, particularly crucial in augmented reality (AR) and virtual reality (VR) systems. We propose a novel eye-tracking ap…
