NONLINEAR DYNAMICS OF FLUCTUATING TWO-DIMENSIONAL MATERIALS IN ACTION

Introduction

Two-dimensional (2D) materials are unique platforms for studying fundamental science. They bridge the gap between the world of atomic scale dynamics and the world of macroscopic mechanical vibrations. Owing to their small size, they can enable exploration of research areas that lie at the forefront of classical and quantum technologies.

Challenges

However, their noisy and nonlinear nature limits their performance. This combination of fluctuations and nonlinearities brings to light a new regime of mechanics that has remained largely untapped. If well understood, this regime can open a wide range of trajectories in high-performance sensing and lab-on-a-chip devices.

Project Goals

NCANTO aims at elucidating the strong interplay between nonlinearities and noise at the atomic scale. The project will leverage the acquired knowledge to engineer 2D nanomechanical devices that:

1. Offer extreme frequency stability.
2. Enable robust and highly-sensitive single-cell sensing.

Research Approach

To realize this vision, I will explore the influence of a range of nonlinear dynamic phenomena on two important noise sources, namely frequency fluctuations and biological noise. My approach will combine state-of-the-art modelling and experimental techniques to deliver novel designs that utilize nonlinear dynamic phenomena at their core.

Expected Outcomes

These designs will:

• Quench frequency noise in 2D resonators for breakthrough performance.
• Enhance biological rhythms at the single-cell level for robust drug screening.

By linking stochastic dynamics, nanomechanics, nonlinear dynamics, and structural optimization, I will develop a multidisciplinary research area that will enable a groundbreaking leap forward in the utilization of 2D materials as nonlinear sensors in frequency-based metrology and bio-health.

Conclusion

NCANTO will thus not only herald new frontiers in nanomechanics but will also open new routes towards engineering nanotools for rapid screening tests in drug development and personalized medicine.
