The authors employ Quantum Monte Carlo simulations to study the scaling behavior of the magnetic structure factor and other observables in a 2D quantum critical magnet coupled to a single cavity mode. They find that while the quantum critical point remains unchanged, critical fluctuations are significantly enhanced and a fractional scaling exponent deviates from expectations based on perturbation theory.
