abstract
Coupling tailored electromagnetic fluctuations to materials provides a resource for controlling correlated quantum matter. By structuring the frequency, spatial, and modal distribution of fluctuations through a new generation of cavity quantum materials, vacuum and thermal spectra can shift phase boundaries and stabilize or suppress orders. This review organizes the field around a fluctuation-focused perspective, surveying a practical design toolbox and recent milestones, and outlining theory-experiment challenges in realistic, multimode, beyond-long-wavelength regimes. We highlight photonic observables and map opportunities for equilibrium and driven control across superconducting, magnetic, moire, and topological platforms.

Record deep-strong coupling (normalized ratio >1.6) realized in 3D Kane fermion Landau polaritons, with gauge-invariant theory showing emergent A² term that precludes superradiant quantum phase transition.
An exactly solvable model of a quantum chain coupled to a cavity photon via dipole interaction yields a closed-form reduced density matrix that reveals logarithmic light-matter and spatial entanglement scaling with system size at strong coupling, arising from photon resolution of collective dipole P
Cavity-mediated attractive interactions enhance the fractional quantum Hall transport gap with a quadratic electron-number scaling and a fourth-power dependence on the vacuum-field gradient, as shown by composite-fermion calculations.
Hyperbolic polariton modes coupled to a Fermi liquid produce a spectral sideband and a λ0 suppression of quasiparticle weight, while the leading pairing and velocity renormalization contributions cancel.
Cavity photons screen attractive or repulsive interactions in a quantum-dot Kitaev chain, allowing the system to reach the sweet spot for poor man's Majorana bound states.
Cavity engineering increases superfluid weight and shifts the superconducting onset temperature upward in an underdoped YBCO thin film, interpreted via a phase-fluctuating superconductor model.
Cavity vacuum fluctuations renormalize bands to switch the dominant pairing channel from singlet to triplet above a critical light-matter coupling.
Construction of a cryogenic UHV tunable confocal Fabry-Pérot cavity apparatus with intracavity 2D sample positioning for enhanced light-matter coupling experiments.
