Sala, R.; Brouard, S.; Muga, J. G. The influence functional: Application to tunnelling. (English) Zbl 0878.60086 J. Phys. A, Math. Gen. 28, No. 21, 6233-6244 (1995). Summary: The influence functional is introduced as a kernel in an integral equation that gives the probability density at time \(t\) and position \(q\) in terms of the initial probability density. This functional is applied to tunnelling through a square barrier to determine the influence, at different times, of various regions of the incident packet on the transmitted peak.
