Universal Frame Potential Hierarchy in Critical Projected Ensembles
Hui-Huang Chen
Local measurements transform a many body wavefunction into a statistical ensemble of conditional quantum states. In chaotic systems, the higher moments of such ensembles diagnose t…

Entanglement of excited states after measurements in conformal field theory
Hui-Huang Chen
We study the entanglement of low-energy excited states after a fixed-outcome projective measurement on a spatial interval in a (1+1)-dimensional conformal field theory (CFT). We re…
