The aim of this paper is to try to corroborate the qualitative results suggested by the Fig. 1 with special attention on the attractive case with finite energy whose asymptotic analysis in time have not been discussed in the previous literature. Let us summarize the techniques used through this pape ...

Deviations from exponential law and Van Hove`s “2t” limit
... The purpose of this paper is to consider the e ects that arise when the coupling constant is small but nonvanishing. This will enable us to give general estimates for deviations from exponential behavior. The paper is organized as follows. We shall rst look, in Section 2, at a simple system: we sum ...
