Research paperExperimental CharacterizationTheoreticalFrequency Stability of Graphene Nonlinear Parametric OscillatorEnise Kartal, Oriel Shoshani, Elena Botnaru, Alberto Martín-Pérez et al.arXiv preprint·2026·10.1021/acs.nanolett.6c00581·arXiv:2602.02476AbstractHigh-frequency stability is crucial for the performance of graphene resonators in sensing and timekeeping applications. The paper demonstrates that graphene parametric oscillators can improve short-term frequency stability in the nonlinear regime, with lower Allan deviation than Duffing oscillations at comparable amplitudes. The work attributes this improvement to strong nonlinear damping and supports it with a minimal theoretical model of phase diffusion.Read more
