Symmetry breaking and error correction in open quantum systems

S Lieu, R Belyansky, JT Young, R Lundgren… - Physical Review Letters, 2020 - APS
Symmetry-breaking transitions are a well-understood phenomenon of closed quantum
systems in quantum optics, condensed matter, and high energy physics. However, symmetry …

Dissipative phase transitions and passive error correction

YJ Liu, S Lieu - Physical Review A, 2024 - APS
We classify different ways to passively protect classical and quantum information, ie, we do
not allow for syndrome measurements, in the context of local Lindblad models for spin …

Geometry and response of Lindbladians

VV Albert, B Bradlyn, M Fraas, L Jiang - Physical Review X, 2016 - APS
Markovian reservoir engineering, in which time evolution of a quantum system is governed
by a Lindblad master equation, is a powerful technique in studies of quantum phases of …

Symmetries and conservation laws in quantum trajectories: Dissipative freezing

C Sánchez Muñoz, B Buča, J Tindall… - Physical Review A, 2019 - APS
In driven-dissipative systems, the presence of a strong symmetry guarantees the existence
of several steady states belonging to different symmetry sectors. Here we show that when a …

Dissipation-driven quantum phase transitions and symmetry breaking

J Hannukainen, J Larson - Physical Review A, 2018 - APS
By considering a solvable driven-dissipative quantum model, we demonstrate that
continuous phase transitions in dissipative systems may occur without an accompanying …

Dissipative prethermal discrete time crystal

DD Vu, S Das Sarma - Physical Review Letters, 2023 - APS
An ergodic system subjected to an external periodic drive will be generically heated to
infinite temperature. However, if the applied frequency is larger than the typical energy scale …

Lindbladians with multiple steady states: theory and applications

VV Albert - arxiv preprint arxiv:1802.00010, 2018 - arxiv.org
Markovian master equations, often called Liouvillians or Lindbladians, are used to describe
decay and decoherence of a quantum system induced by that system's environment. While a …

Breaking strong symmetries in dissipative quantum systems: Bosonic atoms coupled to a cavity

CM Halati, A Sheikhan, C Kollath - Physical Review Research, 2022 - APS
In dissipative quantum systems, strong symmetries can lead to the existence of conservation
laws and multiple steady states. In this Letter we investigate a strong symmetry for bosonic …

Symmetry-protected coherent relaxation of open quantum systems

M van Caspel, V Gritsev - Physical Review A, 2018 - APS
We compute the effect of Markovian bulk dephasing noise on the staggered magnetization
of the spin-1 2 XXZ Heisenberg chain, as the system evolves after a Néel quench. For …

Interacting lattice systems with quantum dissipation: A quantum Monte Carlo study

Z Yan, L Pollet, J Lou, X Wang, Y Chen, Z Cai - Physical Review B, 2018 - APS
Quantum dissipation arises when a large system can be split in a quantum system and an
environment to which the energy of the former flows. Understanding the effect of dissipation …
