Twisted polaritonic crystals in thin van der Waals slabs
Nathaniel Capote-Robayna, Olga Matveeva, Valentyn S. Volkov +2
Polaritons - hybrid light-mater excitations - are very appealing for the confinement of light at the nanoscale. Recently, different kinds of polaritons have been observed in thin s…
Twist-tunable Polaritonic Nanoresonators in a van der Waals Crystal
O. G. Matveeva, A. I. F. Tresguerres-Mata, R. V. Kirtaev +8
Optical nanoresonators are fundamental building blocks in a number of nanotechnology applications (e.g. in spectroscopy) due to their ability to efficiently confine light at the na…
Negative reflection of polaritons at the nanoscale in a low-loss natural medium
Gonzalo Alvarez-Perez, Jiahua Duan, Javier Taboada-Gutierrez +10
Negative reflection occurs when light is reflected towards the same side of the normal to the boundary from which it is incident. This exotic optical phenomenon, which provides a n…
