Exact solution of the compressed hydrogen atom
Autor: J. M. Ferreyra, C. R. Proetto
Publikováno v: American Journal of Physics. 81:860-865
The exact solution to the problem of a hydrogen atom confined in a spherical well (CHA) is discussed; the standard results for the unconfined hydrogen atom (UHA) are recovered as the sphere size becomes large compared to the Bohr radius. The solution

One-body electronic states in nanoscopic rings
Autor: Z. Barticevic, C. R. Proetto, J. Simonin, G. Fuster
Publikováno v: physica status solidi (c). 1:S70-S73
We analyze two possible confining potentials for nanoscopic rings. We compare here the displaced parabola (Hill) and the “centrifugal core” (Vulcan) confining potentials. The corresponding eigenvalues are analyzed as a function of ring radius and

centres in low dimensions: the strong-confinement approach
Autor: C Büsser, C R Proetto
Publikováno v: Journal of Physics: Condensed Matter. 8:L131-L138
Negatively charged centres () formed in semiconductors by attaching a second electron to a shallow neutral hydrogenic donor () have been analysed in the quasi-zero- and quasi-one-dimensional limits. On the basis of the present and already known resul

Transmission and reflection of holes from barriers and wells in semiconductor heterostructures
Autor: A D Sanchez, C R Proetto
Publikováno v: Journal of Physics: Condensed Matter. 7:2059-2079
The quantum mechanical problem of tunnelling and reflection of holes from barriers and wells in semiconductor heterojunctions has been analysed. By using the Luttinger Hamiltonian to describe the dynamics of holes, the inherent anisotropy, non-parabo

Landau levels in the presence of a potential barrier
Autor: J M Ferreyra, C R Proetto
Publikováno v: Journal of Physics: Condensed Matter. 6:6623-6636
The exact solution to the problem of electrons under the combined effect of a square potential barrier and magnetic field parallel to the interfaces has been obtained. Beyond the states associated with the presence of an isolated interface, a new fam

Local pair model for the analysis of tunnelling and photoemission experiments in the normal state of high Tc superconductors
Autor: B. R. Alascio, C. I. Ventura, C. R. Proetto, R. Allub
Publikováno v: Solid State Communications. 77:949-952
We analyze tunnelling and high resolution photoemission results in the normal phase of high T c superconductors. The analysis is based on a “mixed Fermion-Boson” model, in which a band of paired states overlaps the Fermi level of a wider Fermion
