Quantum reflection time and the Goos-Hänchen effect
D. Sokolovski, A. Uranga, Y. Caudano
We explore the analogy between following the motion of a reflected wave packet, and a quantum measurement of the spatial delay imposed on the particle by the scattering potential.…

Quantum weak values and the 'which way?' question
A. Uranga, E. Akhmatskaya, D. Sokolovski
Uncertainty principle forbids one to determine which of the two paths a quantum system has travelled, unless interference between the alternatives had been destroyed by a measuring…

Imaginary past of a quantum particle moving on imaginary time
Anton Uranga, Elena Akhmatskaya, Dmitri Sokolovski
The analytical continuation of classical equations of motion to complex times suggests that a tunnelling particle spends in the barrier an imaginary duration . Does…
