Intrinsic plasmon canalization in the biaxial van der Waals crystal MoOCl
Farid Aghashirinov, Andrea Mancini, Lin Nan +4
Anisotropic polaritons in low-symmetry crystals allow for subwavelength confinement and directional routing of light. The most extreme form of such anisotropy arises at the topolog…

Visible-frequency hyperbolic plasmon polaritons in a natural van der Waals crystal
Giacomo Venturi, Andrea Mancini, Nicola Melchioni +2
Controlling light at subwavelength scales is one of the main challenges of nanophotonics. Leveraging hyperbolic polaritons supporting arbitrarily large wavevectors can lead to extr…

Electromechanical response of saddle points in twisted hBN moiré superlattices
Stefano Chiodini, Giacomo Venturi, James Kerfoot +6
In twisted layered materials (t-LMs), an inter-layer rotation can break inversion symmetry and create an interfacial array of staggered out-of-plane polarization due to AB/BA stack…
