Scattering amplitudes for the rationally extended PT symmetric complex potentials [PDF]
, 2016 In this paper, we consider the rational extensions of two different classes of P T symmetric complex potentials namely the asymptotically vanishing Scarf II and asymptotically non-vanishing Rosen–Morse II [ RM-II] and obtain the accompanying bound state ...

Smooth elastic contact of cylinders by caustics: the contact length in the Brazilian disc test
Archives of Mechanics, 2013 The smooth contact of two elastic cylinders compressed against each other along a common generatrix is studied analytically and experimentally. The main objective is the quantification of the length of the contact arc. For the analytic study, the complex

Eigenvalue bounds for Schr\"odinger operators with complex potentials. III [PDF]
, 2015 We discuss the eigenvalues $E_j$ of Schr\"odinger operators $-\Delta+V$ in $L^2(\mathbb R^d)$ with complex potentials $V\in L^p ...

Spectral stability of Schrödinger operators with subordinated complex potentials [PDF]
Journal of Spectral Theory, 2015 We prove that the spectrum of Schroedinger operators in three dimensions is purely continuous and coincides with the non-negative semiaxis for all potentials satisfying a form-subordinate smallness condition.

Bifurcation of Soliton Families from Linear Modes in Non‐ PT ‐Symmetric Complex Potentials [PDF]
, 2015 Continuous families of solitons in the nonlinear Schrödinger equation with non‐ PT ‐symmetric complex potentials and general forms of nonlinearity are studied analytically. Under a weak assumption, it is shown that stationary equations for solitons admit

Multisoliton interactions for the Manakov system under composite external potentials; pp. 368–378 [PDF]
Proceedings of the Estonian Academy of Sciences, 2015 The soliton interactions of Manakov soliton trains subjected to composite external potentials are modelled by the perturbed complex Toda chain (PCTC). The model is applied to several classes of potentials, such as: (i) harmonic, (ii) periodic, (iii) â ...

Supersymmetry-generated complex optical potentials with real spectra [PDF]
, 2013 We show that the formalism of supersymmetry (SUSY), when applied to parity-time (PT) symmetric optical potentials, can give rise to novel refractive index landscapes with altogether non-trivial properties. In particular, we find that the presence of gain

Vector solitons in nonparity-time-symmetric complex potentials.
Optics Express, 2018 The existence and stability of vector solitons in non-parity-time (PT)-symmetric complex potentials are investigated. We study the vector soliton family, in which the propagation constants of the two components are different.
