Derived categories of Quot schemes on smooth curves and tautological bundles

We define a categorical action of the shifted quantum loop group of ${\mathfrak{s}\mathfrak{l}}_2$ on the derived categories of Quot schemes of finite length quotient sheaves on a smooth projective curve. As an application, we obtain a semi-orthogonal decomposition of the derived categories of Quot schemes, of representation theoretic origin. We use this decomposition to calculate the cohomology of interesting tautological vector bundles over the Quot scheme.
