Tunnelling of plane waves through a square barrier
J. Julve, F. J. de Urries
The time evolution of plane waves in the presence of a 1-dimensional square quantum barrier is considered. Comparison is made between the cases of an infinite and a cut-off (shutte…
Infinite plane wave evolution in a 1-D square quantum barrier
J. Julve, F. J. de Urries
We analytically compute the time evolution of an initial infinite plane wave in the presence of a 1-dimensional square quantum barrier. This calculation generalizes the analysis of…
Time of arrival through a quantum barrier
J. Leon, J. Julve, P. Pitanga +1
We introduce a formalism for the calculation of the time of arrival t at a detector of particles traveling through interacting environments. We develop a general formulation that e…
Higher-derivative scalar field theories as constrained second-order theories
F. J. de Urries, J. Julve
As an alternative to the covariant Ostrogradski method, we show that higher-derivative relativistic Lagrangian field theories can be reduced to second differential-order by writing…
