Dynamics of amorphous membranes in the two-dimensional limit
Liga Jasulaneca, Alberto Martín-Pérez, Alberto Mart\'ın-Pérez +8
Atomically thin mechanical resonators have been realized predominantly in crystalline two-dimensional (2D) materials, such as graphene, where long-range crystalline order sets thei…
Optomechanical tuning of nonlinearity in graphene resonators
Alberto MartÃn-Pérez, Peter G. Steeneken, Farbod Alijani
Graphene resonators exhibit unique mechanical and electrical properties, making them promising candidates for next-generation sensing applications. Here, we introduce an optomechan…
Experimental Quantification of Nonlinear Mode Coupling in Nanomechanical Resonators using Multi-tone Excitation
Chris F. D. Wattjes, Zichao Li, Minxing Xu +3
Nonlinear modal interactions in resonant systems govern a wide range of phenomena, with broad relevance across modern physics and engineering. Yet, experimentally determining the s…
A machine learning framework for uncovering stochastic nonlinear dynamics from noisy data
Matteo Bosso, Giovanni Franzese, Kushal Swamy +3
Modeling real-world systems requires accounting for noise - whether it arises from unpredictable fluctuations in financial markets, irregular rhythms in biological systems, or envi…
Cascade of Modal Interactions in Nanomechanical Resonators with Soft Clamping
Zichao Li, Minxing Xu, Richard A. Norte +3
We uncover a chain of nonlinear modal interactions in softly clamped nanostring resonators. The process involves the sequential coupling of five mechanical modes, during frequency…
Frequency Stability of Graphene Nonlinear Parametric Oscillator
Enise Kartal, Oriel Shoshani, Elena Botnaru +3
High-frequency stability is crucial for the performance of graphene resonators in sensing and timekeeping applications. However, the extreme miniaturization and high mechanical com…
