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…

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…

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…

Fluctuation Spectrum of 2+1D Critical Fermi Surface and its Application to Optical Conductivity and Hydrodynamics

Haoyu Guo

We extend the kinetic operator formalism developed in the companion paper [H.Guo,arXiv:2311.03455] to study the general eigenvalues of the fluctuation normal modes. We apply the fo…

Is the Migdal-Eliashberg Theory for 2+1D Critical Fermi Surface Stable?

Haoyu Guo

We diagnose the stability of the Migdal-Eliashberg theory for a Fermi surface coupled to a gapless boson in 2+1 dimensions. We provide a scheme for diagonalizing the Bethe-Salpeter…
