"Exotic nonlinear supersymmetry and integrable systems"

Exotic nonlinear supersymmetry is characterized by supercharges to be higher order differential operators,

and thus has a nature of a hidden symmetry. We review some aspects of nonlinear supersymmetry and related

to it exotic supersymmetry and nonlinear superconformal symmetry. Examples of reflectionless, finite-gap

and perfectly invisible PT-symmetric zero-gap systems, as well as rational deformations of the quantum

harmonic oscillator and conformal mechanics, are considered, in which such symmetries are realized.
