On the skeleton method and an application to a quantum scissor
Horia D. Cornean, Pierre Duclos, Benjamin Ricaud
In the spectral analysis of few one dimensional quantum particles interacting through delta potentials it is well known that one can recast the problem into the spectral analysis o…
Optimally localized Wannier functions for quasi one-dimensional nonperiodic insulators
H. D. Cornean, A. Nenciu, G. Nenciu
It is proved that for general, not necessarily periodic quasi one dimensional systems, the band position operator corresponding to an isolated part of the energy spectrum has discr…
Classical and quantum dynamics for 2D-electromagnetic potentials asymptotically homogeneous of degree zero
Horia Cornean, Ira Herbst, Erik Skibsted
We consider a charged particle moving in the plane subject to electromagnetic potentials with non-vanishing radial limits. We analyse the classical and the quantum dynamics for lar…
Optical second harmonic generation from Wannier excitons
Thomas G. Pedersen, Horia D. Cornean
Excitonic effects in the linear optical response of semiconductors are well-known and the subject of countless experimental and theoretical studies. For the technologically importa…
