Raising optical Schrödinger's cat with a cavity QED system
Engineering macroscopic quantum state of light is an important goal in quantum optics. However, generating such photonic states in a deterministic way turns out to be hard, as photon-photon and atom-p...

Entanglement of random hypergraph states
Random quantum states and operations are of fundamental and practical interests. In this work, we investigate the entanglement properties of random hypergraph states, which generalize the notion of gr...

Large-N theory of critical Fermi surface and strange metal
We describe the large N saddle point, and the structure of fluctuations about the saddle point, of a theory containing a sharp, critical Fermi surface in twospatial dimensions. The theory describes th...

Random Matrix Methods for Machine Learning: “Lossless” Compression of Large Neural Networks
The advent of the Big Data era has triggered a renewed interest in large-dimensional machine learning (ML) and (deep) neural networks. These methods, being developed from small-dimensional intuitions,...

Resonant thermal Hall effect of phonons coupled to dynamical defects
Recent thermal transport measurements in various materialsincluding pseudogap cuprates have observed large thermal Hall effects which are attributed to phonons. In this talk, I will review some recent...
