abstract = {<p style="text-align: justify;">We define and investigate, via numerical analysis, a one dimensional toy-model
of a cloud chamber. An energetic quantum particle, whose initial state is a superposition
of two identical wave packets with opposite average momentum, interacts
during its evolution and exchanges (small amounts of) energy with an array of localized
spins. Triggered by the interaction with the environment, the initial superposition
state turns into an incoherent sum of two states describing the following situation: or
the particle is going to the left and a large number of spins on the left side changed their
states, or the same is happening on the right side. This evolution is reminiscent of what
happens in a cloud chamber where a quantum particle, emitted as a spherical wave by
a radioactive source, marks its passage inside a supersaturated vapour-chamber in the
form of a sequence of small liquid bubbles arranging themselves around a possible
classical trajectory of the particle.</p>},
