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…
Light Bipolarons Stabilized by Peierls Electron-Phonon Coupling
John Sous, Monodeep Chakraborty, Roman V. Krems +1
It is widely accepted that phonon-mediated high-temperature superconductivity is impossible at ambient pressure, because of the very large effective masses of polarons/bipolarons a…
Electronic band structure engineering in InAs/InSbAs and InSb/InSbAs superlattice heterostructures
Atanu Patra, Monodeep Chakraborty, Anushree Roy
We report a detailed ab initio study of two superlattice heterostructures, one component of which is a unit cell of CuPt ordered InSb_(0.5)As_(0.5). This alloy part of the heterost…
Bulk band inversion and surface Dirac cones in LaSb and LaBi : Prediction of a new topological heterostructure
Urmimala Dey, Monodeep Chakraborty, A. Taraphder +1
We perform \textit{ab initio} investigations of the bulk and surface band structures of LaSb and LaBi and resolve the existing disagreements about the topological property of LaSb,…
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…
Mapping of Electronic Band Gap along the Axis of Single InAs/InSbxAs1-x Heterostructured Nanowire
Atanu Patra, Monodeep Chakrobarty, Anushree Roy
We report the graded electronic band gap along the axis of individual heterostructured WZ-ZB InAs/InSb0.12As0.88 nanowires. Resonance Raman imaging has been exploited to map the ax…
