We review the construction and use of complex potentials in reactive scattering and other
molecular collisions to calculate continuum quantities (such as state-to-state transition …

The issue of tunneling time is replete with controversy and paradoxes. The controversy
stems from the fact that many tunneling time definitions seem to predict superluminal …

The arrival time is a simple classical concept, very common in laboratory practice. This
review describes theoretical problems encountered in trying to obtain a quantum …

We are often told that quantum phenomena demand radical revisions of our scientific world
view and that no physical theory describing well defined objects, such as particles described …

It is argued that there is a sensible way to define conditional probabilities in quantum
mechanics, assuming only Bayes's theorem and standard quantum theory. These …

A unified time analysis of photon and nonrelativistic particle tunnellings is presented, in
which time is regarded as a quantum observable, canonically conjugated to energy. Within …

Recent experimental studies with microwave and laser pulses have revealed superluminal
(faster-than-light) group, signal and energy velocities for the tunneling of electromagnetic …

Quantum transients are temporary features of matter waves before they reach a stationary
regime. Transients may arise after the preparation of an unstable initial state or due to a …

Using the time parameter in the time-dependent Schrödinger equation, we study the time of
flight for a particle tunneling through a square barrier potential. Comparing the mean and …
