[QOART seminar (17-Jul-2026 at 4:00pm MSK)] Nonlinear eigenvalue problems arising in the theory of nonlinear guided waves by S.V. Tikhov
Dear colleagues,
We are pleased to announce the next online seminar on QOART (Quantum optics and related topics)!
Title of the talk: Nonlinear eigenvalue problems arising in the theory of nonlinear guided waves
Speaker: S.V. Tikhov
Abstract:
In this report we consider the propagation of monochromatic electromagnetic waves in a planar waveguide filled with media exhibiting strong self-focusing effect. These waves, known as nonlinear guided waves (NGWs), have been widely studied since at least the early 1980s. In the report we focus on three types of such waves: TE-polarized NGWs, TM-polarized NGWs, and so-called hybrid nonlinear TE-TE waves. From mathematical point of view, these phenomena are described by nonlinear eigenvalue problems. The main objective of the report is to address two questions. The first is: how many solutions (eigenvalues) do these problems have. The second question is: how are these eigenvalues distributed.
Date and time: 17-Jul-2026 at 4:00pm Moscow time
Duration: 30-90 mins
Language: The talk will be delivered in English
