Abstract

This study aims to achieve unidirectional exciton-polariton transport by harnessing the non-Hermitian skin effect—a novel phenomenon in open quantum systems. By integrating 2D materials to form hybridized exciton-photon states, the project seeks to realize weak and strong coupling between excitonic and photonic states that propagate in a single direction, thereby breaking the Lorentz reciprocity theorem. The experimental approach centers on meticulous sample fabrication and emission measurements, culminating in the integration of 2D materials with non-Hermitian photonic crystals. Successful demonstration of this effect could pave the way for significant advancements in quantum computing, secure communications, and energy-efficient optical circuitry.
