Quantum backflow in biased tight-binding systems
Francisco Ricardo Torres Arvizu, Adrián Ortega, Hernán Larralde
We study the phenomenon of quantum backflow in tight-binding systems with complex couplings, considering different boundary conditions and lattice sizes. Backflow is an intrinsical…

On the energy density in quantum mechanics
Francisco Torres Arvizu, Adrian Ortega, Hernán Larralde
There are several definitions of energy density in quantum mechanics. These yield expressions that differ locally, but all satisfy a continuity equation and integrate to the value…
