Cím:                     Quantum secrets of strong-field ionization: quantum
interference and the non-zero tunnel exit momentum
Időpont:             2021. május 28., 9 óra

Az előadás rövid összefoglalója:

The problems of tunneling time and tunnel exit momentum in strong-field
ionization are of outstanding importance regarding both quantum theory and
attosecond metrology. Based on a phase space analysis and the relevant energy
distribution, we reveal the importance of quantum interference between
tunneling and over-the-barrier pathways of escape during the liberation of a
single atomic electron by a linearly polarized laser pulse, which explains
experimentally measured non-zero values of the tunnel exit momentum. We
suggest and justify improved initial conditions for a classical particle
approximation of strong-field ionization, based on the quantum momentum
function, and we show how to reconstruct them from the detected momentum of an
escaped electron.
