An Algebraic Formulation of Quantum Decoherence
M. A. Castagnino, A. R. Ordoniez
Abstract
An algebraic formalism for quantum decoherence in systems with continuous evolution spectrum is introduced. A certain subalgebra, dense in the characteristic algebra of the system, is defined in such a way that Riemann-Lebesgue theorem can be used to explain decoherence in a well defined final pointer basis.
