📚 My Research

My research focuses primarily on driven-dissipative few-body physics. Specifically, I apply Floquet perturbative expansions to interacting bosonic systems to extract non-equilibrium stationary states (NESS). The fluctuations of these NESS can then be analyzed using linear response theory. Additionally, I explore the optimal transition paths between two NESS in driven-dissipative systems under Markovian noise.

Internal Resonance

Fluctuation instabilities via internal resonance in a multimode membrane as a mechanism for frequency combs

We study internal resonances in a membrane nanoelectromechanical system, revealing a phononic frequency comb. Using a pump-noisy-probe technique and theoretical modeling, we uncover significant squeezing, bimodality, and limit cycle formation. Our findings have implications for advanced sensing technologies and novel phononic metamaterials.

Floquet Theory

Floquet expansion by counting pump photons

We develop a Floquet expansion framework for interacting bosonic driven systems, surpassing standard approaches by addressing the quantum-classical mismatch and extending beyond the rotating wave approximation. Our method improves the accuracy of multiphoton resonance positions, crucial for qubit architecture calibration.
