Wave packets, "negative times" and the elephant in the room
D. Sokolovski, A. Matzkin
Controversy surrounding the "tunnelling time problem" stems from the seeming inability of quantum mechanics to provide, in the usual way, a definition of the duration a particle is…

Quantum statistical effects in one-particle densities: scattering and pair production
X. Gutiérrez de la Cal, M. Alkhateeb, M. Pons +2
We study space-time resolved densities of particle-hole pairs produced by an external time-dependent field acting on non-interacting non-relativistic particles. It is shown that, a…

Relativistic Quantum Field Theory Approach to Wavepacket Tunneling: Lack of Superluminal Transmission
M. Alkhateeb, X. Gutierrez de la Cal, M. Pons +2
We investigate relativistic wavepacket dynamics for an electron tunneling through a potential barrier employing space-time resolved solutions to relativistic quantum field theory (…
