Trapped electrons in the quantum degenerate regime | | Ronen Kroeze

3 Aug 2015 | | Abstract: | A full strength Coulomb interaction between trapped electrons can be felt
only in absence of a neutralizing background. In order to study quantum
degenerate electrons without such a background, an external trap is needed to
compensate for the strong electronic repulsion. As a basic model for such a
system, we study a trapped electron pair in a harmonic trap with an explicit
inclusion of its Coulomb interaction. We find the eigenenergies of the system
for any value of the trapping strength. The problem is solved either
numerically or by using approximate methods. As function of the trapping
strength a crossover can be made from the strongly to the weakly-coupled
regime, and we show that in both regimes perturbative methods based on a
pair-wise electron description would be effective for a many-particle trapped
electron system. | | Source: | arXiv, 1508.0365 | | Services: | Forum | Review | PDF | Favorites | |
