Query: Tunneling time in attosecond experiments and time-energy uncertainty
  relation   In this work we present a theoretical model supported with a physical
reasoning leading to a relation which performs an excellent estimation for the
tunneling time in attosecond and strong field experiments, where we address the
important case of the He-atom \cite{Eckle:2008s,Eckle:2008}. Our tunneling time
estimation is found by utilizing the time-energy uncertainty relation and
represents a quantum clock. The tunneling time is also featured as the time of
passage (at the exit of the tunnel) similarly to the Einstein's {\it photon box
Gedanken experiment}. Our work tackles an important study case for the theory
of time in quantum mechanics and is very promising for the search for a
(general) time operator in quantum mechanics. The work can be seen as a new
fundamental step in dealing with the tunneling time in strong field and
ultra-fast science, and is appealing for more elaborate treatments using
quantum wave packet dynamics and especially for complex atoms and molecules.
