## Many-body QED: Unraveling computational complexities of light and matter

We explore novel light-matter quantum systems to probe emergent phenomena of strongly-correlated quantum systems and push the boundaries of light, matter, and complexity.

## 1. Design background field with non-trivial constraints 2. dress with counterpart quantum fluctuation

### waveguide qed

Massive photons in 1D and 2D photonic crystal media (substrate) interacting with neutral atom arrays

### many-body qed

Strongly-interacting Rydberg atoms (substrate) coupled to optical cavity photons

### simple quantum systems coupled to many-body baths

Upgrade all-to-all mean-field quantum systems with dissipative gadgets
