Van Hove's "λ^2 t" limit in nonrelativistic and relativistic field-theoretical models

Van Hove's "λ^2 t" limiting procedure is analyzed in some interesting quantum field theoretical cases, both in nonrelativistic and relativistic models. We look at the deviations from a purely exponential behavior in a decay process and discuss the subtle issues of state preparation and initial time.
