Fractal Energy Spectrum of a Polariton Gas in a Fibonacci Quasiperiodic Potential
Fractal Energy Spectrum of a Polariton Gas in a Fibonacci Quasiperiodic Potential
We report on the study of a polariton gas confined in a quasiperiodic one-dimensional cavity, described by a Fibonacci sequence. Imaging the polariton modes both in real and reciprocal space, we observe features characteristic of their fractal energy spectrum such as the opening of minigaps obeying the gap labeling theorem …
