Particularities of polaron formation in the extended Holstein model with next nearest neighbor transfer
Monodeep Chakraborty, Jayita Chatterjee, Holger Fehske
Employing a largely unbiased variational exact diagonalization technique, we analyze the consequences of longer-ranged electron hopping and electron-phonon interaction on polaron f…
Effect of different site energies on polaronic properties
Jayita Chatterjee, A. N. Das
Using the perturbation method based on a variational phonon basis obtained by the modified Lang-Firsov (MLF) transformation, the two-site single polaron Holstein model is studied i…
Spin-polaron model: transport properties of EuB
Jayita Chatterjee, Unjong Yu, B. I. Min
To understand anomalous transport properties of EuB, we have studied the spin-polaron Hamiltonian incorporating the electron-phonon interaction. Assuming a strong exchange inte…
Role of the superexchange interaction in magnetic transition and polaron crossover
Jayita Chatterjee, A. N. Das
The Hubbard-Holstein model is studied including double-exchange interaction and superexchange interaction using a variational phonon basis obtained through the modified Lang-Firsov…
Two-site two-electron Holstein model: a perturbation study
Jayita Chatterjee, A. N. Das
The two-site two-electron Holstein model is studied within a perturbation method based on a variational phonon basis obtained through the modified Lang-Firsov (MLF) transformation.…
Perturbative expansion using variational phonon basis for Holstein model
Jayita Chatterjee, A. N. Das, P. Choudhury
A simple variational displacement phonon basis, obtained through the modified Lang-Firsov (MLF) transformation, is proposed to study the Holstein model.This phonon basis contains o…
