Abstract

Controlling quantum phases of materials with vacuum field fluctuations in engineered cavities is a topical method for the optical manipulation of emergent phenomena. Here we demonstrate cavity-induced anisotropies in the electronic transport of a high-mobility two-dimensional electron system in a strong magnetic field. In particular, we show the suppression of longitudinal resistivity well below the resistivity at zero magnetic field. These cavity-induced effects occur at ultralow temperatures when the magnetic field lies between quantized Hall plateaus. We interpret our results as arising from the stabilization of thermally disordered quantum Hall stripes. Therefore, our work presents a demonstration of the cavity quantum electrodynamics control of a correlated electronic phase.
