Scattering 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 کاملOn 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 کاملControlled generation of high-intensity optical rogue waves by induced modulation instability
Optical rogue waves are featured as the generation of high amplitude events at low probability in optical systems. Moreover, the formation of optical rogue waves is unpredictable and transient in photonic crystal fibers. In this paper, we put forward a method to generate high-intensity optical rogue waves in a more controlled way based on induced modulation instability, which can suppress the n...
متن کاملModulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons
Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...
