On Scattering from Localized non-Hermitian Potentials
We highlight the conceptual issues that arise when one applies the quasi-Hermitian framework to analyze scattering from localized non-Hermitian potentials, in particular complex square-wells or deltafunctions. When treated in the framework of conventional quantum mechanics, these potentials are generally considered as effective theories, in which probability is not conserved because of processe...
متن کاملScattering theory using smeared non-Hermitian potentials
Complex, non-Hermitian potentials V (x) 6= V (x) can often generate the standard, normalizable bound states ψ(x). Unfortunately, the idea [based on the use of a nonlocal ad hoc metric Θ(x, x) 6= δ(x − x) in Hilbert space] cannot directly be transferred to scattering [cf. H. F. Jones, Phys. Rev. D 78, 065032 (2008)]. We complement and modify this result by showing that a return to the causal and...

متن کاملVirtual Reshaping and Invisibility in Obstacle Scattering
We consider reshaping an obstacle virtually by using transformation optics in acoustic and electromagnetic scattering. Among the general virtual reshaping results, the virtual minification and virtual magnification are particularly studied. Stability estimates are derived for scattering amplitude in terms of the diameter of a small obstacle, which implies that the limiting case for minification...
متن کاملNon-blind acoustic invisibility by dual layers of homogeneous single-negative media
Non-blind invisibility cloaks allowing the concealed object to sense the outside world have great application potentials such as in high-precision sensing or underwater camouflage. However the existing designs based on coordinate transformation techniques need complicated spatially-varying negative index or intricate multi-layered configurations, substantially increasing the difficulty in pract...
