Dynamic localization in Glauber-Fock lattices
S. Longhi, A. Szameit
Glauber-Fock lattices refer to a special class of semi-infinite tight-binding lattices with inhomogeneous hopping rates which are found in certain simple solid-state, quantum optic…
Transparency at the interface between two isospectral crystals
S. Longhi, G. Della Valle
Reflection at an interface separating two different media is a rather universal phenomenon which arises because of wave mismatching at the interface. By means of supersymmetric qua…
Absence of Floquet scattering in oscillating non-Hermitian potential wells
S. Longhi, G. Della Valle
Scattering of a quantum particle from an oscillating barrier or well does not generally conserve the particle energy owing to energy exchange with the photon field, and an incoming…
Invisible defects in complex crystals
S. Longhi, G. Della Valle
We show that invisible localized defects, i.e. defects that can not be detected by an outside observer, can be realized in a crystal with an engineered imaginary potential at the d…
