ABSTRACT
Two-electron lateral quantum dots is a quantum mechanical two-dimensional analogue of the three-dimensional helium atom. When the con ning potential contains two wells, it compares correspondingly to a at version of the H2 molecule. Since electron-electron interaction plays an even more prominent role in two-dimensional systems, as compared to three-dimensional atoms and molecules, the study of quantal few-body structures in two dimensions is of fundamental interest in its own right. It may reveal new insights into the role of strongly correlated dynamics. Other con ning potentials can also be constructed that have a less direct atomic or molecular analogue, for example, “quantum rings” (Viefers et al., 2003).
