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 (…

Computational quantum field theory for fermion pair creation in 2-dimensional curved spacetimes
Mohammed Alkhateeb, James P. Edwards, Yves Caudano
Similarly to the well-known phenomenon of particle / anti-particle pair production in strong electromagnetic fields (the Schwinger effect), the naïve matter field vacuum state can…

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…
