Monitoring derivation of the quantum linear Boltzmann equation
Klaus Hornberger, Bassano Vacchini
We show how the effective equation of motion for a distinguished quantum particle in an ideal gas environment can be obtained by means of the monitoring approach introduced in [EPL…
Three-dimensional Monte Carlo simulations of the quantum linear Boltzmann equation
Heinz-Peter Breuer, Bassano Vacchini
Recently the general form of a translation-covariant quantum Boltzmann equation has been derived which describes the dynamics of a tracer particle in a quantum gas. We develop a st…
Covariant Mappings for the Description of Measurement, Dissipation and Decoherence in Quantum Mechanics
Bassano Vacchini
The general formalism of quantum mechanics for the description of statistical experiments is briefly reviewed, introducing in particular position and momentum observables as POVM c…
Relaxation dynamics of a quantum Brownian particle in an ideal gas
Bassano Vacchini, Klaus Hornberger
We show how the quantum analog of the Fokker-Planck equation for describing Brownian motion can be obtained as the diffusive limit of the quantum linear Boltzmann equation. The lat…
Quantum theory: the role of microsystems and macrosystems
L. Lanz, B. Vacchini, O. Melsheimer
We stress the notion of statistical experiment, which is mandatory for quantum mechanics, and recall Ludwig's foundation of quantum mechanics, which provides the most general frame…
