Static magneto-polarizability of cylindrical nanostructures
S. Pleutin, A. A. Ovchinnikov
The static polarizability of cylindrical systems is shown to have a strong dependence on a uniform magnetic field applied parallel to the tube axis. This dependence is demonstrated…
Excitonic Strings in one dimensional organic compounds
S. Pleutin
Important questions concern the existence of excitonic strings in organic compounds and their signatures in the photophysics of these systems. A model in terms of Hard Core Bosons…
Matrix Product Approach to Conjugated Polymers
M. A. Martin-Delgado, G. Sierra, S. Pleutin +1
The Matrix Product method (MPM) has been used in the past to generate variational ansatzs of the ground state (GS) of spin chains and ladders. In this paper we apply the MPM to stu…
Molecular crystal approach for pi-conjugated polymers: from PPP Hamiltonian to Holstein model for polaron states
S. Pleutin, J-L Fave
Starting from the -electron Pariser-Parr-Pople (PPP) Hamiltonian which includes both strong electron-phonon and electron-electron interactions, we propose some strongly correlat…
A simplified picture for Pi electrons in conjugated polymers : from PPP Hamiltonian to an effective molecular crystal approach
S. Pleutin, J. L. Fave
An excitonic method proper to study conjugated oligomers and polymers is described and its applicability tested on the ground state and first excited states of trans-polyacetylene,…
