The Kossakowski Matrix and Strict Positivity of Markovian Quantum Dynamics
Julián Agredo, Franco Fagnola, Damiano Poletti
We investigate the relationship between strict positivity of the Kossakowski matrix, irreducibility and positivity improvement properties of Markovian Quantum Dynamics. We show tha…
The Generalized Fibonacci Oscillator as an Open Quantum System
Franco Fagnola, Chul Ki Ko, Hyun Jae Yoo
We consider an open quantum system with Hamiltonian whose spectrum is given by a generalized Fibonacci sequence weakly coupled to a Boson reservoir in equilibrium at inverse…
The decoherence-free subalgebra of Gaussian Quantum Markov Semigroups
Julián Agredo, Franco Fagnola, Damiano Poletti
We demonstrate a method for finding the decoherence-subalgebra of a Gaussian quantum Markov semigroup on the von Neumann algebra $\mathcal{B}(Γ(\mathbb{C…
Mathematical Models of Markovian Dephasing
Franco Fagnola, John E. Gough, Hendra I. Nurdin +1
We develop a notion of dephasing under the action of a quantum Markov semigroup in terms of convergence of operators to a block-diagonal form determined by irreducible invariant su…
Relationships between the decoherence-free algebra and the set of fixed points
F. Fagnola, E. Sasso, V. Umanita'
We show that, for a Quantum Markov Semigroup (QMS) with a faithful normal invariant state, the atomicity of the decoherence-free subalgebra and environmental decoherence are equiva…
Entropy production and detailed balance for a class of quantum Markov semigroups
Franco Fagnola, Rolando Rebolledo
We give an explicit entropy production formula for a class of quantum Markov semigroups, arising in the weak coupling limit of a system coupled with reservoirs, whose generators $\…
