Role of long-range coupling on the properties of single polarons in models with dual electron-phonon couplings
Monodeep Chakraborty, Sankeerth S. Narayan, Vigneshwaran R. +1
We use the Variational Exact Diagonalization to investigate the single polaron properties for four different dual models, combining a short-range off-diagonal (Peierls) plus a long…
Holstein polarons and triplet bipolarons with NNN hopping
Monodeep Chakraborty, A. Taraphder, Mona Berciu
We study the ground state of 1D Holstein single polaron with next nearest neighbour electron hopping (NNN), employing a variational approximation based on exact diagonalization. Ou…
Orbital Effects of Strong Magnetic Field on a 2-D Holstein Polaron
S. Pradhan, Monodeep Chakraborty, A. Taraphder
We investigate the orbital effects of strong external magnetic field on the ground state properties of a two dimensional holstein polaron, employing variational approaches based on…
Interacting Holstein and extended-Holstein bipolarons
Monodeep Chakraborty, Masaki Tezuka, B. I. Min
Employing the recently developed self-consistent variational basis generation scheme, we have investigated the bipolaron-bipolaron interaction within the purview of Holstein-Hubbar…
A new self-consistent basis generation scheme for polaron and bipolaron systems
Monodeep Chakraborty, B. I. Min
We have developed a new self-consistent scheme of generating variational basis based on the exactdiagonalization, which can be applied efficiently to various types of electron-phon…
Half Metallicity in PrSrMnO: A first Principle study
M. Chakraborty, P. Pal, B. R. Sekhar
In this communication we present a first principle study of PrSrMnO with . While the parent compounds of this system are antiferromagnetic insulators wi…
Near Fermi level Electronic Structure of PrSrMnO: Photoemission Study
P. Pal, M. K. Dalai, R. Kundu +3
In this study, we report the observation of a pseudogap associated with the insulator-metal transition in compositions of PrSrMnO system with no charge ordering. Ou…
