We collaborate with Vilnius university, Newcastle university, and IAMS to demonstrate the generation and dynamical control of synthetic Landau levels and robust chiral edge states for neutral dark-state polaritons using electromagnetically induced transparency in our theoretical studies. We adopt an optical approach to produce synthetic magnetic fields for dark-state polaritons in the static laboratory frame. In our scalable system, an Aharonov-Bohm phase is obtained along a closed loop in a continuous material rather than a sophisticated lattice structure. Our scheme paves the way toward versatile quantum simulators, dynamically controllable photonic circuits, and generators for exotic states of light carrying topological winding numbers.
Figure. The evolution of (a) initially rightward dark state polariton (DSP) entering the medium at (x, y) = ( -2mm, 0). The subsequent snapshot at 0.2ms of the DSP edge state by (b) out-of-plane and (c)(d) into-plane synthetic magnetic field turned on at 0.038ms. In (d) the DSP bypasses the vacuum area illustrated by the white dashed square.
