Quantum times of arrival for multiparticle states
A. D. Baute, I. L. Egusquiza, J. G. Muga
Using the concept of crossing state and the formalism of second quantization, we propose a prescription for computing the density of arrivals of particles for multiparticle states,…

Moller operators and Lippmann-Schwinger equations for step-like potentials
A. D. Baute, I. L. Egusquiza, J. G. Muga
The Moller operators and the asociated Lippman-Schwinger equations obtained from different partitionings of the Hamiltonian for a step-like potential barrier are worked out, compar…
