Density of a gas of spin polarized fermions in a magnetic field
S. Foulon, F. Brosens, J. T. Devreese +1
For a fermion gas with equally spaced energy levels that is subjected to a magnetic field, the particle density is calculated. The derivation is based on the path integral approach…
Shape-induced magnetic anisotropy in dilute magnetic alloys
V. N. Gladilin, V. M. Fomin, J. T. Devreese
We extend the theory of the surface-induced magnetic anisotropy to mesoscopic samples with arbitrary geometry. The shape-induced anisotropy of impurity spins in small brick-shaped…
Many-polaron system confined to a quantum dot: ground-state energy and optical absorption
J. T. Devreese, S. N. Klimin, V. M. Fomin +1
We find for the first time the ground state energy and the optical absorption spectra for N electrons (holes) interacting with each other and with the longitudinal optical (LO) pho…
Bipolaron Binding in Quantum Wires
E. P. Pokatilov, V. M. Fomin, J. T. Devreese +2
A theory of bipolaron states in quantum wires with a parabolic potential well is developed applying the Feynman variational principle. The basic parameters of the bipolaron ground…
Addendum on rotational properties of confined bosons: time-inversion referencing
F. Brosens, J. T. Devreese, L. F. Lemmens
In this addendum we introduce the concept of time-inversion referencing. This is an extension of hypertext allowing authors to cite papers that where not yet published (or even not…
Comment on: rotational properties of trapped bosons
F. Brosens, J. T. Devreese, L. F. Lemmens
Based on the Hellman-Feynman theorem it is shown that the average square radius of a cloud of interacting bosons in a parabolic well can be derived from their free energy. As an ap…
Quantum transport in the cylindrical nanosize silicon-based MOSFET
S. N. Balaban, E. P. Pokatilov, V. M. Fomin +6
A model is developed for a detailed investigation of the current flowing through a cylindrical nanosize MOSFET with a close gate electrode. The quantum mechanical features of the l…
Optical Absorption of an Interacting Many-Polaron Gas
J. Tempere, J. T. Devreese
The optical absorption of a many (continuum) polaron gas is derived in the framework of a variational approach at zero temperature and weak or intermediate electron-phonon coupling…
Many Body Diffusion and Interacting Electrons in a Harmonic Confinement
F. Luczak, F. Brosens, J. T. Devreese +1
We present numerically exact energy estimates for two-dimensional electrons in a parabolic confinement. By application of an extension of the recently introduced many-body diffusio…
