A Time Dependent Local Isospin Density Approximation Study of Asymmetric Nuclear Matter

Enrico Lipparini, Francesco Pederiva

The dynamic response of asymmetric nuclear matter is studied by using a Time-Dependent Local Isospin Density (TDLIDA) approximation approach. Calculations are based on a local dens…

The Effect of Interactions on the Conductance of Graphene Nanoribbons

M. Bazzanella, P. Faccioli, E. Lipparini

We study the effects of the interaction between electrons and holes on the conductance G of quasi-one-dimensional graphene systems. We first consider as a benchmark the limit in wh…

Quantum Monte Carlo study of circular quantum dots in presence of Rashba interaction

A. Ambrosetti, F. Pederiva, E. Lipparini

We present the numerical Quantum Monte Carlo results for the ground state energy of circular quantum dots in which Rashba spin-orbit iteraction is present. Diffusion Monte Carlo wi…

Spin-orbit excitations of quantum wells

A. Ambrosetti, J. M Escartin, E. Lipparini +1

Confinement asymmetry effects on the photoabsorption of a quantum well are discussed by means of a sum-rules approach using a Hamiltonian including a Rashba spin-orbt coupling. We…

Quantum Monte Carlo study of the two-dimensional electron gas in presence of Rashba interaction

A. Ambrosetti, F. Pederiva, E. Lipparini +1

We introduce a variant to the Diffusion Monte Carlo algorithm that can be employed to study the effects of the Rashba interaction in a many electron systems. Because of the spin--o…

Optical response of two-dimensional few-electron concentric double quantum rings: A local-spin-density-functional theory study

Francesc Malet, Martí Pi, Manuel Barranco +2

We have investigated the dipole charge- and spin-density response of few-electron two-dimensional concentric nanorings as a function of the intensity of a perpendicularly applied m…
