 Description I will show several applications of nonlinearly realized supersymmetry. Firstly, I will discuss the connection of nonlinear supersymmetry to anti-D3 brane in string theory. In particular, I will show that the anti-D3 brane coupled to KKLT background can be described in terms of nonlinear realizations/ constrained superfields. Secondly, I will discuss the application of nonlinear supersymmetry to cosmological model building. We will focus on the recently proposed model dubbed as "anti-D3 brane induced geometric inflation" in which the inflation potential is given by the Kahler geometric mixing between inflaton and Goldstino superfield.
