Analytic structure of the S-matrix for singular quantum mechanics
(American Institute of Physics, 2015-05)
The analytic structure of the S-matrix of singular quantum mechanics is examined within a multichannel framework, with primary focus on its dependence with respect to a parameter (Ω) that determines the boundary conditions. ...
Multichannel framework for singular quantum mechanics
(Academic Press Inc Elsevier Science, 2014-01)
A multichannel S-matrix framework for singular quantum mechanics (SQM) subsumes the renormalization and self-adjoint extension methods and resolves its boundary-condition ambiguities. In addition to the standard channel ...

The problem of the classical limit of quantum mechanics and the role of self-induced decoherence
(Springer, 2006-12)
Our account of the problem of the classical limit of quantum mechanics involves two elements. The first one is self-induced decoherence, conceived as a process that depends on the own dynamics of a closed quantum system ...
