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 (…
Quantum measurements and delays in scattering by zero-range potentials
X. Gutiérrez de la Cal, M. Pons, D. Sokolovski
Eisenbud-Wigner-Smith delay and the Larmor time give different estimates for the duration of a quantum scattering event. The difference is most pronounced in the case where de-Brog…
