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…
