Interpolating State in String Field Theory

We derive an oscillator form for the Butterflies in terms of Sliver matrix S and its twisted version T as was already done for the Wedges in term of T . We write a General Squeezed state depending on a matrix U and we show in a compact way the interpolation between Identity state and the Sliver and between the Nothing state and the Sliver, growing in powers of T and S matrices, respectively, in the choice of such matrix U . Furthermore, we define a class of states which we call Laguerre states and we give a formal derivation of such interpolating state in terms of them.
