Introduction to tunneling times and to weak measurements

Introduction to tunneling times and to weak measurements. How does one actually measure time ? (recall: there is no operator for time) How long does it take a particle to tunnel through a forbidden region? Classically: time diverges as energy approaches barrier height.

BECs, lasers, and other clocks. Some remarks on time measurement (&c.). BECs versus lasers Do Bose-Einstein condensates have a macroscopic phase? Do lasers have a definite phase? What does have a phase? How can it be measured? Does any of this make a difference?
