Shell filling in non-linear magneto-tunneling spectroscopy of vertical quantum dots
B. Jouault, G. Faini, A. Angelucci +6
We report on non-linear magneto-tunneling experiments carried out in single GaAs vertical quantum dots. We show that conduction at low voltage bias can be a spectroscopic tool for…
Addition energies of a Quantum Dot with harmonic electron-electron interactions
Antimo Angelucci, Arturo Tagliacozzo
We study a two dimensional electron system in a parabolic confining potential and constant magnetic field for the case of harmonic electron-electron interaction. We present analyti…
Some exact results for the multicomponent t-J model
Antimo Angelucci, Sandro Sorella
We present a generalization of the Sutherland's multicomponent model. Our extension includes both the ferromagnetic and the antiferromagnetic t-J model for any value of the exchang…
Effective lattice actions for correlated electrons
Antimo Angelucci
We present an exact, unconstrained representation of the electron operators in terms of operators of opposite statistics. We propose a path--integral representation for the -…
Large physical spin approach for strongly correlated electrons
A. Angelucci, S. Sorella, D. Poilblanc
We present a novel approach for a systematic large--spin expansion of the - Hamiltonian which enables us to work without the constraint of no double occupancy. In our scheme…
Phase separation in the large-spin {\it t}-{\it J} model
Antimo Angelucci, Sandro Sorella
We investigate the phase diagram of the two dimensional {\it t}-{\it J} model using a recently developed technique that allows to solve the mean-field model hamiltonian with a vari…
