Full configuration interaction approach to the few-electron problem in artificial atoms
Massimo Rontani, Carlo Cavazzoni, Devis Bellucci +1
We present a new high-performance configuration interaction code optimally designed for the calculation of the lowest energy eigenstates of a few electrons in semiconductor quantum…
Variable resistance at the boundary between semimetal and excitonic insulator
Massimo Rontani, L. J. Sham
We solve the two-band model for the transport across a junction between a semimetal and an excitonic insulator. We analyze the current in terms of two competing terms associated wi…
Coherent transport in homojunction between excitonic insulator and semimetal
Massimo Rontani, L. J. Sham
From the solution of a two-band model, we predict that the thermal and electrical transport across the junction of a semimetal and an excitonic insulator will exhibit high resistan…
The Crossover between Liquid and Solid Electron Phases in Quantum Dots: A Large-Scale Configuration-Interaction Study
Massimo Rontani, Carlo Cavazzoni, Guido Goldoni
We study the crossover between liquid and solid electron phases in a two-dimensional harmonic trap as the density is progressively diluted. We infer the formation of geometrically…
Imaging quasi-particle wavefunctions in quantum dots via tunneling spectroscopy
Massimo Rontani, Elisa Molinari
We show that in quantum dots the physical quantities probed by local tunneling spectroscopies, namely the quasi-particle wavefunctions of interacting electrons, can considerably de…
