Topologically Protected Polaritonic Bound State in the Continuum
Harsh Gupta, Tatiana Contino, Mingze He +4
Bound states in the continuum (BICs) have emerged as powerful tools to realize ultra-high-Q resonances in nanophotonics. While previous implementations have primarily relied on die…
Mode Conversion of Hyperbolic Phonon Polaritons in van der Waals terraces
Byung-Il Noh, Sina Jafari Ghalekohneh, Mingyuan Chen +7
Electromagnetic hyperbolicity has driven key functionalities in nanophotonics, including super-resolution imaging, efficient energy control, and extreme light manipulation. Central…
Superluminal Correlations in Ensembles of Optical Phase Singularities
Tomer Bucher, Alexey Gorlach, Arthur Niedermayr +16
Phase singularities are universal features found across diverse wave systems. Their ensembles exhibit distance correlations governing exotic material phases. However, the full corr…
Exciton self-trapping in twisted hexagonal boron nitride homostructures
Sébastien Roux, Christophe Arnold, Etienne Carré +17
One of the main interests of 2D materials is their ability to be assembled with many degrees of freedom for tuning and manipulating excitonic properties. There is a need to underst…
Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
