Breakdown of Fermi's Golden Rule in 1d systems at non-zero temperature
Thomas Young, Jerome LLoyd, Curt von Keyserlingk
In interacting quantum systems, the single-particle Green's function is expected to decay in time due to the interaction induced decoherence of quasiparticles. In the limit of weak…
Enforced Gaplessness from States with Exponentially Decaying Correlations
Rahul Sahay, Curt von Keyserlingk, Ruben Verresen +1
It is well known that an exponentially localized Hamiltonian must be gapless if its ground state has algebraic correlations. We show that even certain exponentially decaying correl…
Thermalization rates and quantum Ruelle-Pollicott resonances: insights from operator hydrodynamics
Carolyn Zhang, Laimei Nie, Curt von Keyserlingk
In thermalizing many-body quantum systems without conservation laws such as ergodic Floquet and random unitary circuits, local expectation values are predicted to decay to their eq…
Dissipation-assisted operator evolution method for capturing hydrodynamic transport
Tibor Rakovszky, C. W. von Keyserlingk, Frank Pollmann
We introduce the dissipation-assisted operator evolution (DAOE) method for calculating transport properties of strongly interacting lattice systems in the high temperature regime.…
Operator Spreading in Quantum Maps
Sanjay Moudgalya, Trithep Devakul, C. W. von Keyserlingk +1
Operators in ergodic spin-chains are found to grow according to hydrodynamical equations of motion. The study of such operator spreading has aided our understanding of many-body qu…
