We conduct research in both high-energy physics and quantum information. Our goal is to advance quantum theories of gravity (holographic principle), with quantum entanglement, complexity, and chaos as central concepts.
Toward this goal, we focus on three objectives:
Emergent spacetime from quantum entanglement and observables
Krylov subspace method for quantum complexity and computation
Quantum simulation of holographic phases and black holes
We use AdS/CFT and SYK models as our primary theoretical laboratories. Our tools are quantum field theory, general relativity, and machine learning.
