Analyzing the spin-bath model without simulations
Sebastian Fortin, Olimpia Lombardi
On the basis of a lemma designed to decide whether a discrete system decoheres or not with no need of computer simulations, in this paper we analyze the well-known spin-bath model.…
Predicting decoherence in discrete models
Mario Castagnino, Sebastian Fortin
The general aim of this paper is to supply a method to decide whether a discrete system decoheres or not, and under what conditions decoherence occurs, with no need of appealing to…
Foundations of quantum mechanics: decoherence and interpretation
Olimpia Lombardi, Juan Sebastián Ardenghi, Sebastian Fortin +1
In this paper we review Castagnino's contributions to the foundations of quantum mechanics. First, we recall his work on quantum decoherence in closed systems, and the proposal of…
On a possible definition of the moving preferred basis
Mario Castagnino, Sebastian Fortin
There are many formalisms to describe quantum decoherence. However, many of them give a non general and ad hoc definition of "pointer basis" or "moving preferred basis", and this f…

What are the systems that decohere?
Mario Castagnino, Sebastian Fortin, Olimpia Lombardi
The fact that the Environment Induced Decoherence approach offers no general criterion to decide where to place the "cut" between system and environment has been considered as a se…
