Open quantum systems for quarkonia [PDF]
International Journal of Modern Physics A, 2021 I review recent applications of the open quantum system framework in the understanding of quarkonium suppression in heavy-ion collisions, which has been used as a probe of the quark–gluon plasma for decades. The derivation of the Lindblad equations for quarkonium in both the quantum Brownian motion and the quantum optical limits and their ...

Operator growth and Krylov construction in dissipative open quantum systems [PDF]
Journal of High Energy Physics, 2022 Inspired by the universal operator growth hypothesis, we extend the formalism of Krylov construction in dissipative open quantum systems connected to a Markovian bath.

Digital Simulation of Single Qubit Markovian Open Quantum Systems: A Tutorial
Quanta, 2023 One of the first proposals for the use of quantum computers was the simulation of quantum systems. Over the past three decades, great strides have been made in the development of algorithms for simulating closed quantum systems and the more complex open

Defining Stable Phases of Open Quantum Systems [PDF]
Physical Review X, 2023 The steady states of dynamical processes can exhibit stable nontrivial phases, which can also serve as fault-tolerant classical or quantum memories. For Markovian quantum (classical) dynamics, these steady states are extremal eigenvectors of the non ...

Operator growth in open quantum systems: lessons from the dissipative SYK [PDF]
Journal of High Energy Physics, 2022 We study the operator growth in open quantum systems with dephasing dissipation terms, extending the Krylov complexity formalism of [ 1 ]. Our results are based on the study of the dissipative q -body Sachdev-Ye-Kitaev (SYK_ q ) model, governed by the ...

A study of quantum correlations in open quantum systems [PDF]
Quantum Information and Computation, 2011 In this work, we study quantum correlations in mixed states. The states studied are modeled by a two-qubit system interacting with its environment via a quantum non demolition (purely dephasing) as well as dissipative type of interaction. The entanglement dynamics of this two qubit system is analyzed.

Taming Quantum Noise for Efficient Low Temperature Simulations of Open Quantum Systems. [PDF]
Physical Review Letters, 2022 The hierarchical equations of motion (HEOM), derived from the exact Feynman-Vernon path integral, is one of the most powerful numerical methods to simulate the dynamics of open quantum systems.

QuantumCumulants.jl: A Julia framework for generalized mean-field equations in open quantum systems [PDF]
Quantum, 2021 A full quantum mechanical treatment of open quantum systems via a Master equation is often limited by the size of the underlying Hilbert space. As an alternative, the dynamics can also be formulated in terms of systems of coupled differential equations ...
