Sensing relativistic quantum fields with minimally perturbing local measurements
F. Daem, L. Ballesteros Ferraz, A. Zampeli +1
We develop a framework for minimally perturbing local measurements in relativistic quantum field theory, with the aim to sense local properties of the field in a non-destructive ma…
Revivals and quantum carpets for the relativistic Schrödinger equation
Benoît Zumer, Florent Daem, Alexandre Matzkin
We investigate wavepacket dynamics for a relativistic particle in a box evolving according to the relativistic Schrödinger (also known as the Salpeter) equation. We derive the solu…
Trajectories in coupled waveguides: an application to a recent experiment and Hiley's lessons on the falsification of the Bohmian model
F. Daem, T. Durt, A. Matzkin
From "surreal" trajectories to which-way measurements, Basil Hiley had a lesson: claims of falsifying the Bohmian model do not withstand scrutiny provided the model is applied corr…
Microcausality and Tunneling Times in Relativistic Quantum Field Theory
Mohammed Alkhateeb, Alex Matzkin
We show, in the framework of a space-time resolved relativistic quantum field theory approach to tunneling, that microcausality precludes superluminal tunneling dynamics. More spec…
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…
Effects of superradiance on relativistic Foldy-Wouthuysen densities
F. Daem, A. Matzkin
Recent interest in the studies of structured states obtained in relativistic electron beams has highlighted the use of two alternative descriptions, each based on a different wavef…
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 (…
Tunneling dynamics of the relativistic Schrodinger/Salpeter equation
F. Daem, A. Matzkin
We investigate potential scattering and tunneling dynamics of a particle wavepacket evolving according to the relativistic Schrödinger equation (also known as the Salpeter equation…
Dynamics, locality and weak measurements: trajectories and which-way information in the case of a simplified double-slit setup
F. Daem, A. Matzkin
Understanding how the interference pattern produced by a quantum particle in Young's double-slit setup builds up -- the "only mystery" of quantum mechanics according to Feynman --…
Evolution of strictly localized states in non-interacting quantum field theories with background fields
M. Alkhateeb, A. Matzkin
We investigate the construction of spin-1/2 fermionic and spin-0 bosonic wave-packets having compact spatial support in the framework of a computational quantum field theory (QFT)…
