Dynamics of impurity in the environment of Dirac fermions

We study the dynamics of a non-magnetic impurity interacting with the surface states of a 3D and 2D topological insulator. Employing the linked cluster technique we develop a formalism for obtaining the Greens function of the mobile impurity interacting with the low-energy Dirac fermions. We show th...
