Topological Control of Polaritonic Flatbands in Anisotropic van der Waals Metasurfaces
Connor Heimig, Thomas Weber, Cristina Cruciano +9
Anisotropic van der Waals (vdW) materials exhibit direction-dependent optical and electronic properties, making them valuable for tailoring directional light-matter interactions. R…
Excitonic Mott transition without population inversion
Oleg Dogadov, Armando Genco, Allison R. Cadore +12
Exciton dissociation via the excitonic Mott transition (EMT) governs the high-density optical response of semiconductors and sets fundamental limits for optoelectronic devices. The…
Integration of 2D Materials in Radial van der Waals Heterostructure Metasurfaces
Connor Heimig, Jonas Biechteler, Cristina Cruciano +12
Two-dimensional semiconductors, such as monolayer transition metal dichalcogenides (TMDC), exhibit strong excitonic transitions at room temperature and offer a unique platform for…
Spin injection and emission helicity switching in a 2D perovskite/WSe2 heterostructure
Jakub Jasinski, Francesco Gucci, Thomas Brumme +16
The initialization and control of a long-lived spin population in lead halide perovskites are prerequisites for their use in spintronic applications. Here, we demonstrate circular…
Ultrafast dynamics of coherent exciton-polaritons in van der Waals semiconductor metasurfaces
Luca Sortino, Armando Genco, Cristina Cruciano +14
Enabling coherent light-matter interactions is a critical step toward next-generation quantum technologies. However, achieving this under ambient temperature conditions remains cha…
Electrically tunable ultrafast dynamics and interactions of hybrid excitons in a 2D semiconductor bilayer
Edoardo Lopriore, Charalambos Louca, Armando Genco +12
Extended efforts have been devoted to the study of strongly-interacting excitons and their dynamics, towards macroscopic quantum states of matter such as Bose-Einstein condensates…
