Decoherence and Classical Behaviour in Quantum Mechanics

  • Gianfausto Dell’Antonio

We discuss the meaning of decoherence and the emergence of a classical behaviour of a quantum system in interaction with an environment. After a brief introduction to the formalism of Quantum Mechanics we present a simple two-particle model where the decoherence effect can be quantitatively evaluated.
