Dielectric engineering enables cavity-mediated exciton hopping
What the study found The study reports mesoscopic exciton-polariton domains in a structured dielectric exciton environment and an effective long-range exciton hopping in the dispersive regime of cavity-coupling. Why the authors say this matters The authors conclude that these findings are a step toward interacting polaritonic networks and quantum simulations in exciton-polariton lattices based on…
Theory predicts trion signatures in ARPES spectra
What the study found The study presents a first theoretical analysis of how trions, or charged excitons, may appear in angle-resolved photoemission spectroscopy (ARPES) spectra of monolayer transition-metal dichalcogenides. It reports that the extra charge carrier changes the spectral position and shape compared with neutral excitons, and that mass-imbalanced trions are predicted to show a…
