Tensor network simulation of chains of non-Markovian open quantum systems [PDF]
Physical Review Research, 2022 We introduce a general numerical method to compute dynamics and multi-time correlations of chains of quantum systems, where each system may couple strongly to a structured environment.

Aspects of non-equilibrium in classical and quantum systems: Slow relaxation and glasses, dynamical large deviations, quantum non-ergodicity, and open quantum dynamics [PDF]
Physica A: Statistical Mechanics and its Applications, 2017 In these four lectures I describe basic ideas and methods applicable to both classical and quantum systems displaying slow relaxation and non-equilibrium dynamics.

Quantum localization in open chaotic systems [PDF]
Physical Review E, 2008 We study a quasi-Floquet state of a $δ$-kicked rotor with absorbing boundaries focusing on the nature of the dynamical localization in open quantum systems. The localization lengths $ξ$ of lossy quasi-Floquet states located near the absorbing boundaries decrease as they approach the boundary while the corresponding decay rates $Γ$ are dramatically ...

Entanglement Degradation in Two Interacting Qubits Coupled to Dephasing Environments
Entropy, 2023 One of the main obstacles toward building efficient quantum computing systems is decoherence, where the inevitable interaction between the qubits and the surrounding environment leads to a vanishing entanglement.

Time-Dependent Variational Principle for Open Quantum Systems with Artificial Neural Networks. [PDF]
Physical Review Letters, 2021 We develop a variational approach to simulating the dynamics of open quantum many-body systems using deep autoregressive neural networks. The parameters of a compressed representation of a mixed quantum state are adapted dynamically according to the ...

Scarring in open quantum systems
Physical Review E, 2008 We study scarring phenomena in open quantum systems. We show numerical evidence that individual resonance eigenstates of an open quantum system present localization around unstable short periodic orbits in a similar way as their closed counterparts. The structure of eigenfunctions around these classical objects is not destroyed by the opening.

Dynamical invariant based shortcut to equilibration in open quantum systems [PDF]
Quantum Science and TechnologyWe propose using the dynamical invariants, also known as the Lewis–Riesenfeld invariants, to speed-up the equilibration of a driven open quantum system. This allows us to reverse engineer the time-dependent master equation that describes the dynamics of ...

Hamiltonian assignment for open quantum systems
Physical Review Research, 2020 We investigate the problem of determining the Hamiltonian of a locally interacting open quantum system. To do so, we construct Hamiltonian estimators based on inverting a set of stationary, or dynamical, Heisenberg-Langevin equations of motion which rely
