Stephanos Venakides
Professor of Mathematics

Fields of work: Pure and applied mathematics, physics and biology. Specific areas: Differential equations,  integrable systems, acoustic and electromagnetic scattering (especially transmission anomalies and resonances), photonic crystals, exciton polaritons and micromagnetics.

Invited as one of the three Abel lecturers in the award of the Abel Prize to Peter Lax, The Norwegian Academy of Science and Letters, Oslo, Norway, May 2005

Current Research Interests

   This area of physics deals with the  magnetic behaviors at micrometer and sub-micrometer length scales. The area is of  significant scientific and technological importance and involves challenging  mathematical questions.  The theory includes the statics and dynamics of topological configurations, e.g.
magnetic vortex  and antivortex states as well as skyrmion states.  I am working collaboratively on the mathematical derivation of skyrmion profiles and  behaviors. Skyrmions are localized structures  of magnetization  on a thin plate of a ferromagnetic or antiferromagnetic medium. They can be stationary, traveling or breathing (pulsating).  The mathematical study seeks to explain experimental results, or discover new phenomena and is assisted by numerical experiments. Besides single skyrmions, our study encompases skyrmion collisions, which exhibit the interesting behavior of ninety degree scattering.  

   The study encompasses acoustic and electromagnetic scattering from a spatially periodic geometry and combines mathematical analysis with numerical calculations.
