Artificial polariton molecules

We show that geometrically coupled polariton condensates fabricated in semiconductor devices are versatile systems capable of simulating molecules with given characteristics. In particular, we consider oscillatory and stationary symmetric asymmetric states dimers, trimers, tetrads their luminosity real Fourier space. The spectral weights associated discrete lines. Their number separation can be controlled by changing the geometry condensates, reflected coupling strengths. also combine continuous degrees freedom one system. degree is represented phase while density asymmetry. Our work paves way to engineer controllable artificial a range properties manufactured on demand.
