Scattering near-field optical microscopy at 1-nm resolution using ultralow tip oscillation amplitudes
Akitoshi Shiotari, Jun Nishida, Adnan Hammud +4
Scattering-type scanning near-field optical microscopy (s-SNOM) allows for the observation of the optical response of material surfaces with a resolution far below the diffraction…
Unidirectional Ray Polaritons in Twisted Asymmetric Stacks
J. Álvarez-Cuervo, M. Obst, S. Dixit +25
The vast repository of van der Waals (vdW) materials supporting polaritons offers numerous possibilities to tailor electromagnetic waves at the nanoscale. The development of twisto…
Extreme light confinement and control in low-symmetry phonon-polaritonic crystals
Emanuele Galiffi, Giulia Carini, Xiang Ni +9
Polaritons are a hybrid class of quasiparticles originating from the strong and resonant coupling between light and matter excitations. Recent years have witnessed a surge of inter…
