Dynamics of Fluctuations in Quantum Simple Exclusion Processes

  title={Dynamics of Fluctuations in Quantum Simple Exclusion Processes},
  author={Denis Bernard and Fabian H L Essler and Ludwig Hruza and Marko Medenjak},
We consider the dynamics of fluctuations in the quantum asymmetric simple exclusion process (Q-ASEP) with periodic boundary conditions. The Q-ASEP describes a chain of spinless fermions with random hoppings that are induced by a Markovian environment. We show that fluctuations of the fermionic degrees of freedom obey evolution equations of Lindblad type, and derive the corresponding Lindbladians. We identify the underlying algebraic structure by mapping them to non-Hermitian spin chains and… Expand
Exact solution of a quantum asymmetric exclusion process with particle creation and annihilation
We consider a Lindblad equation that for particular initial conditions reduces to an asymmetric simple exclusion process with additional loss and gain terms. The resulting Lindbladian exhibitsExpand
Can the Macroscopic Fluctuation Theory be Quantized?
The Macroscopic Fluctuation Theory is an effective framework to describe transports and their fluctuations in classical out-of-equilibrium diffusive systems. Whether the Macroscopic FluctuationExpand
Effects of Quantum Pair Creation and Annihilation on a Classical Exclusion Process: the transverse XY model with TASEP
We investigate how particle pair creation and annihilation, within the quantum transverse XY model, affects the non-equilibrium steady state (NESS) and Liouvillian gap of the stochastic TotallyExpand


Equilibrium fluctuations in maximally noisy extended quantum systems
We introduce and study a class of models of free fermions hopping between neighbouring sites with random Brownian amplitudes. These simple models describe stochastic, diffusive, quantum, unitaryExpand
Open Quantum Symmetric Simple Exclusion Process.
The approach gives a solution of the classical symmetric simple exclusion process based on fermion technology and opens the route towards the extension of the macroscopic fluctuation theory to many-body quantum systems. Expand
Dissipative spin chain as a non-Hermitian Kitaev ladder
We derive exact results for the Lindblad equation for a quantum spin chain (one-dimensional quantum compass model) with dephasing noise. The system possesses doubly degenerate nonequilibrium steadyExpand
Solution of a minimal model for many-body quantum chaos
We solve a minimal model for quantum chaos in a spatially extended many-body system. It consists of a chain of sites with nearest-neighbour coupling under Floquet time evolution. Quantum states atExpand
Integrable Quantum Dynamics of Open Collective Spin Models.
This work considers a collective quantum spin s in contact with Markovian spin-polarized baths using a conserved superoperator charge to find the exact spectrum and eigenmodes of the Liouvillian and exploits the exact solution to characterize steady-state properties. Expand
Operator Hydrodynamics, OTOCs, and Entanglement Growth in Systems without Conservation Laws
Thermalization and scrambling are the subject of much recent study from the perspective of many-body quantum systems with locally bounded Hilbert spaces (`spin chains'), quantum field theory andExpand
Noisy coupled qubits: Operator spreading and the Fredrickson-Andersen model
We study noise-averaged observables for a system of exchange-coupled quantum spins (qubits), each subject to a stochastic drive, by establishing mappings onto stochastic models in the strong-noiseExpand
Coarse-grained dynamics of operator and state entanglement
We give a detailed theory for the leading coarse-grained dynamics of entanglement entropy of states and of operators in generic short-range interacting quantum many-body systems. This includesExpand
Operator Spreading in Random Unitary Circuits
Random quantum circuits yield minimally structured models for chaotic quantum dynamics, which are able to capture, for example, universal properties of entanglement growth. We provide exact resultsExpand
Entangling power of time-evolution operators in integrable and nonintegrable many-body systems
The entangling power and operator entanglement entropy are state-independent measures of entanglement. Their growth and saturation is examined in the time-evolution operator of quantum many-bodyExpand
