Bound-state third-order optical nonlinearities of embedded germanium nanocrystals
Hasan Yildirim, Ceyhun Bulutay
Embedded germanium nanocrystals (NCs) in a silica host matrix are theoretically analyzed to identify their third-order bound-state nonlinearities. A rigorous atomistic pseudopotent…

Enhancement of optical switching parameter and third-order optical nonlinearities in embedded Si nanocrystals: a theoretical assessment
Hasan Yıldırım, Ceyhun Bulutay
Third-order bound-charge electronic nonlinearities of Si nanocrystals (NCs) embedded in a wide band-gap matrix representing silica are theoretically studied using an atomistic pseu…

On the Lie symmetries of Kepler-Ermakov systems
A. Karasu, H. Yildirim
In this work, we study the Lie-point symmetries of Kepler--Ermakov systems presented by C. Athorne in J. Phys. A24 (1991), L1385--L1389. We determine the forms of arbitrary functio…
