Editorial synthesis by the site author across the reading notes below. It is an interpretation, not a finding reported by any single paper. Each note keeps the authors’ findings separate from commentary and links the original source.
Working summary
Exciton–photon coupling and lattice dispersion create polariton bands. Pumping, dissipation and interactions then govern collective behaviour such as condensation.
Connections
Moiré and flat-band engineering connect semiconductor microcavities to collective matter-like behaviour. Coupled oscillators identify hybridization; nonlinear dynamics is a further layer.
Draws on the reading notes for: Condensation in a moiré landscape, Bands, radiation & hybrid modes.
Questions and limits
A spectral anticrossing alone is not proof of condensation. Distinguish strong coupling, polariton condensation and conventional photon lasing.
