Findings
Electron correlations induce new physics in quantum dots.
Quantum dots exhibit similarities and differences with real atoms.
Electron interactions significantly influence quantum dot behavior.
Abstract
The electronic properties of nanoscale quantum dots are reviewed. The similarities and differences between these `artificial atoms' and real atoms are discussed and, in particular, the effect of electron correlations is examined. It is shown that for (semiconductor) quantum dots, with only a few electrons, electron correlations can give rise to important new physics which is absent in their true atomic counterparts.
