Multifractal and Glassy Signatures of Non-Ergodic 2D Quantum Dynamics
Aleksey Lunkin, Nicole S. Ticea, Michael T. Solomon +296
The fate of ergodicity and localization in disordered, interacting quantum systems in two spatial dimensions remains an outstanding open problem in non-equilibrium physics. Theoret…
Energy diffusion in weakly interacting chains with fermionic dissipation-assisted operator evolution
En-Jui Kuo, Brayden Ware, Peter Lunts +2
Interacting lattice Hamiltonians at high temperature generically give rise to energy transport governed by the classical diffusion equation; however, predicting the rate of diffusi…
Comparing numerical methods for hydrodynamics in a one-dimensional lattice spin model
Stuart Yi-Thomas, Brayden Ware, Jay D. Sau +1
In ergodic quantum spin chains, locally conserved quantities such as energy or particle number generically evolve according to hydrodynamic equations as they relax to equilibrium.…
A sharp phase transition in linear cross-entropy benchmarking
Brayden Ware, Abhinav Deshpande, Dominik Hangleiter +4
Demonstrations of quantum computational advantage and benchmarks of quantum processors via quantum random circuit sampling are based on evaluating the linear cross-entropy benchmar…
Subdiffusive hydrodynamics of nearly-integrable anisotropic spin chains
Jacopo De Nardis, Sarang Gopalakrishnan, Romain Vasseur +1
We address spin transport in the easy-axis Heisenberg spin chain subject to integrability-breaking perturbations. We find that spin transport is subdiffusive with dynamical exponen…
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…
