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…
Basic properties of a mean field laser equation
Franco Fagnola, Carlos M. Mora
We study the non-linear quantum master equation describing a laser under the mean field approximation. The quantum system is formed by a single mode optical cavity and two level at…
Quadratic Open Quantum Harmonic Oscillator
Ameur Dhahri, Franco Fagnola, Hyunjae Yoo
We study the quantum open system evolution described by a Gorini-Kossakowski-Sudarshan-Lindblad generator with creation and annihilation operators arising in Fock representations o…
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…
