Polariton BECs: Theory and Concepts

Fabrice Laussy

Much of polariton condensate coherence and correlations arise from linear interference rather than strong interactions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

a significant part of the phenomenology -- including bosonic correlations and coherence buildup -- can often be understood without invoking strong interactions or genuine quantum effects.

C2weakest assumption

That the unique WISI (Weakly-Interacting, Strongly-Interfering) character of polaritons, arising from their light-matter superposition, permits linear non-interacting models to account for observed coherence and correlations in place of interaction-based explanations.

C3one line summary

Surveys theoretical concepts of polariton Bose-Einstein condensates, emphasizing that linear and non-interacting effects explain much of the phenomenology including bosonic correlations and coherence buildup.
