We describe photonic crystal microcavities with very strong light-matter interaction to realize roomtemperature, equilibrium, exciton-polariton Bose-Einstein condensation (BEC). This goal is achieved through a careful balance between strong light trapping in a photonic band gap (PBG) and large exciton density enabled by a multiple quantum-well (QW) structure with a moderate dielectric constant....

For a generic semi-classical laser dynamics in the complex Ginzburg-Landau form, we develop Bogoliubov approach for computation of emission linewidth. Our method provides unifying perspective treatments by Henry and Petermann: both broadening mechanisms are ascribed to non-orthogonality modes, which live space with doubled degrees freedom. As an example application, allows study interplay drive...

In the strong light-matter coupling regime realized, e.g., by integrating semiconductors into optical microcavities, polaritons as new hybrid quasiparticles are formed. The corresponding change in dispersion relation has a large impact on optics, dynamics, and transport behavior of semiconductors. this paper, we investigate strong-coupling hBN-encapsulated ${\mathrm{MoSe}}_{2}$ monolayers focus...

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...

Long range spatial coherence lies at the heart of the remarkable quantum behaviour of matter manifested by superconductors and superfluids at the macroscopic scale. An intriguing question is how quickly the coherent field can be established when a normal incoherent gas is driven through the phase transition. Experimentally, such dynamics are not easily accessible in traditional superconductors ...

A theoretical model is presented which explains the dominant decoherence process in a microcavity polariton condensate. The mechanism which is invoked is the effect of self-phase modulation, whereby interactions transform polariton number fluctuations into random energy variations. The model shows that the phase coherence decay, g(τ), has a Kubo form, which can be Gaussian or exponential, depen...
