Abstract: An error in Klimas & Viñas (J. Plasma Phys., vol. 85 (6), 2019, 905850610) is noted and explained. It is shown that the results in Klimas and Viñas were unaffected by the error. Further ramifications… read more here.

Abstract: Spectral winding of complex eigenenergies represents a topological aspect unique in non-Hermitian systems, which vanishes in one-dimensional (1D) systems under the open boundary conditions (OBC). In this work, we discover a boundary spectral winding in… read more here.

Abstract: The eigenvalue problem for a perturbed two-dimensional resonant oscillator is considered. The exciting potential is given by a nonlocal nonlinearity of Hartree type with smooth self-action potential. To each representation of the rotation algebra corresponds… read more here.
