Benchmarking the cosmological master equations
European Physical Journal C: Particles and Fields, 2022 Master equations are commonly employed in cosmology to model the effect of additional degrees of freedom, treated as an “environment”, onto a given “system”.

Time-Dependent Density Functional Theory of Open Quantum Systems in the Linear-Response Regime [PDF]
, 2010 Time-Dependent Density Functional Theory (TDDFT) has recently been extended to describe many-body open quantum systems (OQS) evolving under non-unitary dynamics according to a quantum master equation.

Exact master equation and non-Markovian decoherence dynamics of Majorana zero modes under gate-induced charge fluctuations [PDF]
, 2017 In this paper, we derive the exact master equation to investigate the decoherence dynamics of Majorana zero modes in the Kitaev model, a 1D $p\,$-wave spinless topological superconducting chain (TSC), that is disturbed by charge fluctuations through gate

Non-Markovian dynamics of a qubit [PDF]
, 2006 In this paper we investigate the non-Markovian dynamics of a qubit by comparing two generalized master equations with memory. In the case of a thermal bath, we derive the solution of the post-Markovian master equation recently proposed in Ref.

Quantum Collision Models: A Beginner Guide
Entropy, 2022 In recent years, quantum collision models, sometimes dubbed repeated interaction models, have gained much attention due to their simplicity and their capacity to convey ideas without resorting to technical complications typical of many approaches and ...

Heisenberg-Langevin versus quantum master equation [PDF]
, 2017 The quantum master equation is an important tool in the study of quantum open systems. It is often derived under a set of approximations, chief among them the Born (factorization) and Markov (neglect of memory effects) approximations.

Which differential equations correspond to the Lindblad equation?
Physical Review Research, 2023 The Lindblad master equation can always be transformed into a first-order linear ordinary differential equation (1ODE) for the coherence vector. We pose the inverse problem: given a finite-dimensional, nonhomogeneous 1ODE, does a corresponding Lindblad ...

Markovian quantum master equation beyond adiabatic regime. [PDF]
Physical Review E, 2016 By introducing a temporal change time scale τ_{A}(t) for the time-dependent system Hamiltonian, a general formulation of the Markovian quantum master equation is given to go well beyond the adiabatic regime.

The Master Equation and the Convergence Problem in Mean Field Games [PDF]
, 2015 This book describes the latest advances in the theory of mean field games, which are optimal control problems with a continuum of players, each of them interacting with the whole statistical distribution of a population. While it originated in economics,
