Measurement-induced phases of matter require feedback
Aaron J. Friedman, Oliver Hart, Rahul Nandkishore
We explore universality and phases of matter in hybrid quantum dynamics combining chaotic time evolution and projective measurements. We develop a unitary representation of measure…
Locality and error correction in quantum dynamics with measurement
Aaron J. Friedman, Chao Yin, Yifan Hong +1
The speed of light sets a strict upper bound on the speed of information transfer in both classical and quantum systems. In nonrelativistic quantum systems, the Lieb-Robinson T…
Fracton magnetohydrodynamics
Marvin Qi, Oliver Hart, Aaron J. Friedman +2
We extend recent work on hydrodynamics with global multipolar symmetries -- known as "fracton hydrodynamics" -- to systems in which the multipolar symmetries are gauged. We refer t…
Subdiffusion and many-body quantum chaos with kinetic constraints
Hansveer Singh, Brayden Ware, Romain Vasseur +1
We investigate the spectral and transport properties of many-body quantum systems with conserved charges and kinetic constraints. Using random unitary circuits, we compute ensemble…
Topological edge modes without symmetry in quasiperiodically driven spin chains
Aaron J. Friedman, Brayden Ware, Romain Vasseur +1
We construct an example of a 1 quasiperiodically driven spin chain whose edge states can coherently store quantum information, protected by a combination of localization, dynami…
Diffusive hydrodynamics from integrability breaking
Aaron J. Friedman, Sarang Gopalakrishnan, Romain Vasseur
We describe the crossover from generalized hydrodynamics to conventional hydrodynamics in nearly integrable systems. Integrable systems have infinitely many conserved quantities, w…
