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 sol…

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 (…

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…

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…
