Free-Fermion Measurement-Induced Volume- to Area-Law Entanglement Transition in the Presence of Fermion Interactions
Matthew S. Foster, Haoyu Guo, Chao-Ming Jian +1
At a generic volume- to area-law entanglement transition in a many-body system, quantum chaos is arrested. We argue that this tends to imply the vanishing of a certain "mass" term…

Fluctuation Spectrum of Critical Fermi Surfaces
Haoyu Guo
We investigate the low-energy effective theory of a Fermi surface coupled to an Ising-nematic quantum critical point in (2+1) spacetime dimensions with translation symmetry. We for…

Quantitative measurement of viscosity in two-dimensional electron fluids
Yihang Zeng, Haoyu Guo, Olivia M. Ghosh +4
Electron hydrodynamics is an emerging framework that describes dynamics of interacting electron systems as conventional fluids. While evidence for hydrodynamic-like transport is re…
