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…

Spectra and transport of probability and energy densities in a -symmetric square well with a delta-function potential
Francisco Ricardo Torres Arvizu, Adrian Ortega, Hernán Larralde
We study the spectrum, eigenstates and transport properties of a simple -symmetric model consisting in a finite, complex, square well potential with a delta…
