Quantum Zeno Effect in Open Quantum Systems [PDF]
Annales Henri Poincaré, 2021 AbstractWe prove the quantum Zeno effect in open quantum systems whose evolution, governed by quantum dynamical semigroups, is repeatedly and frequently interrupted by the action of a quantum operation. For the case of a quantum dynamical semigroup with a bounded generator, our analysis leads to a refinement of existing results and extends them to a ...

Quantum thermo-dynamical construction for driven open quantum systems [PDF]
Quantum, 2021 Quantum dynamics of driven open systems should be compatible with both quantum mechanic and thermodynamic principles. By formulating the thermodynamic principles in terms of a set of postulates we obtain a thermodynamically consistent master equation ...

Sublinear Scaling in Non-Markovian Open Quantum Systems Simulations [PDF]
Physical Review X, 2023 While several numerical techniques are available for predicting the dynamics of non-Markovian open quantum systems, most struggle with simulations for very long memory and propagation times, e.g., due to superlinear scaling with the number of time steps $

Round table on open quantum systems [PDF]
EPJ Web of Conferences, 2022 This is a discussion about open quantum systems and its application to the study of hard probes. It reviews some of the things that were said in the corresponding round table. Views are only my own.

Mixing Time of Open Quantum Systems via Hypocoercivity
Physical Review LettersUnderstanding the mixing of open quantum systems is a fundamental problem in physics and quantum information science. Existing approaches for estimating the mixing time often rely on the spectral gap estimation of the Lindbladian generator, which can be ...

Symmetry Protected Topological Order in Open Quantum Systems [PDF]
Quantum, 2021 We systematically investigate the robustness of symmetry protected topological (SPT) order in open quantum systems by studying the evolution of string order parameters and other probes under noisy channels.

Hilbert space fragmentation in open quantum systems [PDF]
Physical Review Research, 2023 We investigate the phenomenon of Hilbert space fragmentation (HSF) in open quantum systems and find that it can stabilize highly entangled steady states.

Lieb-Schultz-Mattis Theorem in Open Quantum Systems. [PDF]
Physical Review Letters, 2023 The Lieb-Schultz-Mattis (LSM) theorem provides a general constraint on quantum many-body systems and plays a significant role in the Haldane gap phenomena and topological phases of matter.

Current fluctuations in open quantum systems: Bridging the gap between quantum continuous measurements and full counting statistics [PDF]
, 2023 Continuously measured quantum systems are characterized by an output current, in the form of a stochastic and correlated time series which conveys crucial information about the underlying quantum system.

Singular-Value Statistics of Non-Hermitian Random Matrices and Open Quantum Systems [PDF]
PRX Quantum, 2023 The spectral statistics of non-Hermitian random matrices are of importance as a diagnostic tool for chaotic behavior in open quantum systems. Here, we investigate the statistical properties of singular values in non-Hermitian random matrices as an ...
