Decoherence, measurement and interpretation of quantum mechanics
Juan Sebastián Ardenghi, Mario Castagnino, Sebastian Fortin +1
According to our modal-Hamiltonian interpretation (MHI) of quantum mechanics, the Hamiltonian of the closed system defines the set of its definite-valued observables. This definiti…
The effect of random coupling coefficients on decoherence
Mario Castagnino, Sebastian Fortin, Olimpia Lombardi
The aim of this letter is to analyze the effect on decoherence of the randomness of the coupling coefficients involved in the interaction Hamiltonian. By studying the spin-bath mod…
Decoherence as a relative phenomenon: a generalization of the spin-bath model
Mario Castagnino, Sebastian Fortin, Olimpia Lombardi
In this paper we propose a closed-system perspective to study decoherence. From this perspective we analyze the spin-bath model as presented in the literature, and a natural genera…
A general theoretical framework for decoherence in open and closed systems
Mario Castagnino, Sebastian Fortin, Roberto Laura +1
A general theoretical framework for decoherence is proposed, which encompasses formalisms originally devised to deal just with open or with closed systems. The conditions for decoh…
