Interacting quantum systems unveil a wealth of counterintuitive phenomena, from entanglement and superposition to quantum interference. These extraordinary features not only deepen our understanding of quantum mechanics but also provide powerful tools for engineering and manipulating quantum systems. Their potential spans Physics, Computer Science, and Engineering, shaping the future of technology and uncovering new physics.

Our research explores a broad spectrum of Atomic, Molecular, and Optical (AMO) systems, which serve as an ideal platform for studying diverse interacting quantum systems in a controlled setting. These range from contact interactions in neutral atoms to dipolar interactions in polar molecules and Rydberg atom arrays, long-range couplings in trapped-ion crystals and cold atoms confined in high-finesse cavities, and engineered interactions mediated by coherent light. To investigate these complex experimental systems, we employ a combination of analytical methods and numerical techniques—balancing simple models that capture essential physics with sophisticated simulations that account for real-world noise and decoherence.

Below are some ongoing projects and selected publications.
