Confined free-electrons in an applied electric field: Discontinuous electron density
Stephane Pleutin
We consider free electrons in rectangular quantum dots, with either hard wall boundary conditions or anharmonic confinement. In both cases, due to finite size effects, a homogeneou…
Interaction effects on persistent current of ballistic cylindrical nanostructures
S. Pleutin
We consider clean cylindrical nanostructures with an applied longitudinal static magnetic field. Without Coulomb interaction, the field induces, for particular values, points of de…
The electrostatic potential profile along a biased molecular wire: A model quantum mechanical calculation
Stéphane Pleutin, Hermann Grabert, Gert-Ludwig Ingold +1
We study the electrostatic potential of a molecular wire bridging two metallic electrodes in the limit of weak contacts. With the use of a tight-binding model including a fully thr…
Edge-state effects on the magneto-polarizability of nanographite layers
S. Pleutin, A. A. Ovchinnikov
The possibility for carbon materials such as activated carbon fibers or graphite ribbons, to support edge-states could change drastically their magnetic properties. The purpose of…
The Recurrent Variational Approach applied to the Electronic Structure of Conjugated Polymers
S. Pleutin, E. Jeckelmann, M. A. Martin-Delgado +1
In this note, first the Recurrent Variational Approach (RVA) is introduced by using as example a non-trivial spin-model, the spin-1/2 antiferromagnetic two-leg-ladder. Then, a firs…
