Mobility Edges in Photonic Mosaic Lattice

Anderson localization is a basic quantum phenomenon to explain how metal-insulator phase transitions occur in solid-state systems. Recent advances in ultracold atoms and photonic materials have created new opportunities to investigate such phenomena.

The concept of the mobility edge, which separates extended and localized states in the energy spectrum, is essential for understanding localization physics.

In this project, I aim to study mobility edge physics using an integrated photonics platform that is more precise and scalable than atomic systems for modulating the lattice at room temperature.

Additionally, the platform allows for observing quantum correlation induced by particle statistics using multi-photon state excitation.

This proposal seeks to address fundamental questions in ME physics, leading to a deeper understanding of quantum localization, and the technology developed for controlling and detecting photons over a large scale of spatial modes and hybrid integration could have applications in on-chip analog quantum computing and quantum sensing.

I will first explore photonic mosaic lattice with coherent light and analyze the result with the assistance of machine learning algorithm. From the 2nd year, I will start working on quantum light source and fabricate hybrid integrated circuits.

In the 4th year, with all elements ready, I will combine the concept of ME physics with quantum light to explore multi-particle transport in disordered medium.
