Recent work on synchronization phenomena in large-scale disordered laser systems. We found that selectively sparse coupling architectures outperform all-to-all configurations even under the lower coupling budget. The observed scaling laws are explained and predicted by thermodynamic potential theory.

My research leverages reinforcement learning to optimize quantum control policies, aiming to create and stabilize quantum entanglement through a strictly data-driven paradigm. Specifically, I investigate quantum optomechanical systems, modeling linear and nonlinear interactions alongside the effects of weak continuous measurement.

In the $\alpha-T_3$ lattice, the interplay between Landau-Zener (LZ) transitions and Bloch oscillations typically breaks down into irregular Bloch-Zener oscillation patterns. To explain this complex dynamic, we employ the adiabatic-impulse model combined with Landau-Zener-Stückelberg (LZS) interferometry. By analyzing the phase interference mechanisms between consecutive LZ transitions, we unravel the origins of this irregularity. Furthermore, this interferometric framework yields theoretical guidance for tuning the external electric field strength to achieve and control regular macroscopic oscillation patterns.
