Thermodynamic properties of Holstein polarons and the effects of disorder
A. N. Das, S. Sil
The ground state and finite temperature properties of polarons are studied considering a two-site and a four-site Holstein model by exact diagonalization of the Hamiltonian. The ki…

Two-site polaron problem: a perturbation approach with variational basis states
A. N. Das, Jayita Chatterjee
A convergent perturbation method using modified Lang Firsov transformation is developed for a two-site single-polaron system. The method is applicable for the entire range of the e…
