Fluctuations and noise-limited sensing near the exceptional point of $\mathcal{P}\mathcal{T}$-symmetric resonator systems

N. Asger Mortensen, P. A. D. Gonçalves, Mercedeh Khajavikhan +3

We theoretically explore the role of mesoscopic fluctuations and noise on the spectral and temporal properties of systems of $\mathcal{P}\mathcal{T}$-symmetric coupled gain-loss resonators o…
