Entangled electronic states in multiple-quantum-dot systems.

We present an analytically solvable model of P colinear, two-dimensional quantum dots, each containing two electrons. Inter-dot coupling via the electron-electron interaction gives rise to sets of entangled ground states. These ground states have crystal-like inter-plane correlations and arise dis-continously with increasing magnetic field. Their ranges and stabilities are found to depend on dot size ratios, and to increase with P .
