We consider a time-dependent one-dimensional nonlinear Schrödinger equation with a symmetric double-well potential represented by two Dirac's δ. Among our results we give an explicit formula for the integral kernel of the unitary semigroup associated with the linear part of the Hamiltonian. Then we establish the corresponding Strichartz-type estimate and we prove local existence and uniqueness of the solution to the original nonlinear problem.
