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…
Multiple and spectrally robust photonic magic angles in reconfigurable α-MoO3 trilayers
J. Duan, G. Álvarez-Pérez, C. Lanza +8
The assembling of twisted stacks of van der Waals (vdW) materials had led to the discovery of a profusion of remarkable physical phenomena in recent years, as it provides a means t…
Fundamentals of polaritons in strongly anisotropic thin crystal layers
Kirill V. Voronin, Gonzalo Álvarez-Pérez, Christian Lanza +2
Polaritons in strongly anisotropic thin layers have recently captured the attention in nanophotonics because of their directional propagation at the nanoscale, which offers unique…
Terahertz Twistoptics -- engineering canalized phonon polaritons
Maximilian Obst, Tobias Nörenberg, Gonzalo Álvarez-Pérez +11
The terahertz (THz) frequency range is key to study collective excitations in many crystals and organic molecules. However, due to the large wavelength of THz radiation, the local…
