Interacting hydrodynamic modes in spinless fermions with dephasing noise
Fabian H. L. Essler, Patrik Penc
The paper analyzes the non‑equilibrium dynamics of spinless fermions under dephasing noise using a Lindblad framework, mapping the problem to an exactly solvable Hubbard model with…
Quench Spectroscopy of Magnetic Excitations on a Superconducting Quantum Processor
D. A. Millar, G. W. Pennington, N. T. M. Siow +5
The elementary excitation spectrum of a many-body quantum system encodes many key properties, including phenomena as diverse as transport, thermalisation and ground state structure…
Complexity of Quantum Trajectories
Luca Lumia, Emanuele Tirrito, Mario Collura +2
Open quantum systems can be described by unraveling Lindblad master equations into ensembles of quantum trajectories. Here we investigate how the complexity of such trajectories is…
Non-equilibrium quantum dynamics of interacting integrable models by Monte Carlo sampling Lehmann representations
Riccardo Senese, Fabian H. L. Essler
Determining the dynamics of interacting integrable many-particle quantum systems at finite times after homogeneous quantum quenches is a long-standing challenge. We present a Monte…
Exact Quantum Many-Body Scars by a generalized Matrix-Product Ansatz
Sascha Gehrmann, Fabian H. L. Essler
We construct exact eigenstates of quantum many-body systems with Hamiltonians that are not frustration-free in matrix product form, based on a local error cancellation ansatz motiv…
Linear response and exact hydrodynamic projections in Lindblad equations with decoupled Bogoliubov hierarchies
Patrik Penc, Fabian H. L. Essler
We consider a class of spinless-fermion Lindblad equations that exhibit decoupled BBGKY hierarchies. In the cases where particle number is conserved, their late time behaviour is c…
