  In this article, we show that the categorical action of the shifted $q=0$
affine algebra can be used to construct (or induce) t-structures on the weight
categories. The main idea is to interpret the exceptional collection
constructed by Kapranov as convolution of Fourier-Mukai kernels in the
categorical action via using the Borel-Weil-Bott theorem.
  In particular, when the categories are the bounded derived category of
coherent sheaves on Grassmannians. The t-structure we obtain is precisely the
exotic t-structure defined by Bezrukavnikov of the exceptional collections
given by Kapranov. As an application, we calculate the matrix coefficients for
generators of the shifted $q=0$ affine algebra on the basis given by Kapranov
exceptional collections.
