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…
Dissipative Luttinger liquids
Aaron J Friedman
We investigate a one dimensional quantum fluid coupled to a dissipative bath. The quantum fluid is captured by the canonical Luttinger liquid; the bath is given by the model of Cal…
Spectral statistics and many-body quantum chaos with conserved charge
Aaron J. Friedman, Amos Chan, Andrea De Luca +1
We investigate spectral statistics in spatially extended, chaotic many-body quantum systems with a conserved charge. We compute the spectral form factor analytically for a m…
Integrable many-body quantum Floquet-Thouless pumps
Aaron J. Friedman, Sarang Gopalakrishnan, Romain Vasseur
We construct an interacting integrable Floquet model featuring quasiparticle excitations with topologically nontrivial chiral dispersion. This model is a fully quantum generalizati…
Localization-protected order in spin chains with non-Abelian discrete symmetries
Aaron J. Friedman, Romain Vasseur, Andrew C. Potter +1
We study the non-equilibrium phase structure of the three-state random quantum Potts model in one dimension. This spin chain is characterized by a non-Abelian symmetry recent…
Particle-hole symmetry, many-body localization, and topological edge modes
Romain Vasseur, Aaron J. Friedman, S. A. Parameswaran +1
We study the excited states of interacting fermions in one dimension with particle-hole symmetric disorder (equivalently, random-bond XXZ chains) using a combination of renormaliza…
Effect of yttrium substitution on the superconducting properties of the system LaYOFBiS
I. Jeon, D. Yazici, B. D. White +2
We present the effect of yttrium substitution on superconductivity in the LaYOFBiS system. Polycrystalline samples with nomina…
Superconductivity induced by electron doping in the system La1-xMxOBiS2 (M = Ti, Zr, Hf, Th)
D. Yazici, K. Huang, B. D. White +7
We report a strategy to induce superconductivity in the BiS-based compound LaOBiS. Instead of substituting F for O, we increase the charge-carrier density (electron dope) v…
Superconductivity of F-substituted LnOBiS2 (Ln = La, Ce, Pr, Nd, Yb) compounds
D. Yazici, K. Huang, B. D. White +3
Polycrystalline samples of F-substituted LnOBiS2 (Ln = La, Ce, Pr, Nd, Yb) compounds were synthesized by solid-state reaction. The samples were characterized by x-ray diffraction m…
