Ultrafast Control of Lifetime in High Q Anisotropic Plasmon Polaritons
Romain Tirole, Giacomo Venturi, Emroz Khan +6
Losses are a major roadblock in the technological implementation of surface plasmons at optical frequencies. The recent emergence of MoOCl2, a correlated van-der-Waals material wit…
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…
Anisotropic electron gas in a hyperbolic van der Waals material
Nicola Melchioni, Andrea Mancini, Antonio Ambrosio
Electron gases in low dimensional materials exhibit unconventional transport and optical phenomena due to reduced phase space, enhanced interactions, and strong sensitivity to latt…
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…
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…
