Title: Linear and nonlinear epsilon near zero materials - what is so special about them?
Abstract: In this talk I describe the linear and nonlinear optical properties of the “epsilon-near-zero” materials using example of transparent conductive materials like ITO. I show that most of “unusual” properties of these materials can be related to slow group velocity and then I identify the conduction band nonparabolicity as the dominant cause of nonlinearity in them
