The aim of this paper is to discuss in a pedagogical way the problem of the emergence of classical behaviour in certain physical systems which, in principle, are correctly described by quantum mechanics. It is stressed that the limit → 0 is not sufficient and the crucial role played by the environment must be taken into account. In particular, recalled is the old problem raised by Mott in 1929 (Proc. R. Soc. Lond. A 126 79) concerning the straight tracks observed in a cloud chamber, produced by… Expand
A model of a quantum particle in a quantum environment: a numerical study
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 packetsExpand
The Mott Problem in One Dimension
In the α decay of a nucleus, the tracks left in the medium by the α particle are linear, even though its initial wave function is spherically symmetric. Understanding this quantum phenomenon has beenExpand
Tracks in the Cloud Chamber
This chapter is devoted to a historical introduction of the problem of tracks observed in a cloud chamber. Continuing along the lines of the subject we presented in our paper (Figari and Teta 2013),Expand


Trajectories for the wave function of the universe from a simple detector model
Inspired by Mott's (1929) analysis of particle tracks in a cloud chamber, we consider a simple model for quantum cosmology which includes, in the total Hamil- tonian, model detectors registeringExpand
The emergence of classical properties through interaction with the environment
The dependence of macroscopic systems upon their environment is studied under the assumption that quantum theory is universally valid. In particular scattering of photons and molecules turns out toExpand
A Collision Problem in the Wave Mechanics
In the present work the wave mechanics are applied to the discussion of a collision problem of a more complicated type than has, I think, hitherto been done. Though there is nothing very new in theExpand
Quantum equilibrium and the origin of absolute uncertainty
The quantum formalism is a “measurement” formalism-a phenomenological formalism describing certain macroscopic regularities. We argue that it can be regarded, and best be understood, as arising fromExpand
On the mathematical Structure of Quantum Measurement Theory
We show that the key problems of quantum measurement theory, namely the reduction of the wave packet of a microsystem and the specification of its quantum state by a macroscopic measuring instrument,Expand
The Physical Principles of the Quantum Theory
It is an unusual pleasure to present Professor Heisenberg’s Chicago lectures on “The Physical Principles of the Quantum Theory” to a wider audience than could attend them when they were originallyExpand
A solvable model of a tracking chamber
We analyse a quantum system consisting of a particle travelling in a model-environment made up of a net of localised two-level subsystems. We examine the dynamics of the entanglement through whichExpand
Unified dynamics for microscopic and macroscopic systems.
A modified quantum dynamics for the description of macroscopic objects is constructed and it is shown that it forbids the occurrence of linear superpositions of states localized in far-away spatial regions and induces an evolution agreeing with classical mechanics. Expand
The Wave Mechanics of $\alpha $-Ray Tracks
The present note is suggested by a recent paper by Prof. Darwin,* and is intended to show how one of the most typically particle-like properties of matter can be derived from the wave mechanics. InExpand
Joint excitation probability for two harmonic oscillators in one dimension and the Mott problem
We analyze a one dimensional quantum system consisting of a test particle interacting with two harmonic oscillators placed at the positions a1 and a2, with a1>0 and ∣a2∣>a1, in the two possibleExpand
