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 …

In this article, after a theoretical introduction and a sketch of some related long-standing
predictions, a bird's-eye view is presented—with the help of nine figures—of the various …

We study the phenomenon of one-dimensional non-resonant tunneling through two
successive (opaque) potential barriers, separated by an intermediate free region Script R, by …

We revisit the arguments underlying two well-known arrival-time distributions in quantum
mechanics, viz., the Aharonov–Bohm–Kijowski (ABK) distribution, applicable for freely …

The group velocity of evanescent waves (in undersized waveguides, for instance) was
theoretically predicted, and has been experimentally verified, to be superluminal (vg> c). By …

The Hartman effect refers to the rather paradoxical result that the time spent by a quantum
mechanical particle or a photon to tunnel through an opaque potential barrier becomes …

The various experimental sectors of physics in which superluminal motions seem to appear
are briefly mentioned. In particular, a bird's-eye view is presented of the experiments with …

We investigate theoretically the Hartman effect in quantum tunneling through single and
double barriers in a single graphene layer. The numerical results indicate that the Hartman …

Some new results are presented and recent developments are reviewed on the study of
Time in quantum physics as an observable, canonically conjugate to energy. Operators for …

An explicit expression is obtained for the phase-time corresponding to tunneling of a (non-
relativistic) particle through two rectangular barriers, both in the case of resonant and in the …
