Modifying the electronic properties of the topological systems with cavity — •Saber Rostamzadeh, Remi Avriller, Clement Dutreix, and Fabio Pistolesi — Laboratoire Ondes et Matiere d Aquitaine, Universite de Bordeaux, France

Topological systems exhibit fascinating electronic applications due to their distinctive edge and zero-mode states. A central question is how these states interact with various environments, such as intense light. Similarly, hybrid quantum systems containing a few electrons, such as quantum dots, serve as valuable models for engineering topological electronic states. These systems have also garnered significant interest in cavity quantum electrodynamics (cavity QED) for their potential to achieve ultrastrong light-matter interactions. Their simplified architectures offer significant enhancements and optimizations in electron-photon coupling. In this study, we investigate modifications in electronic transport within single and double quantum dot arrays placed inside a cavity.
