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. Interdot coupling via the electron-electron interaction gives rise to sets of entangled ground states. These ground states have crystal-like interplane correlations and arise discontinuously with increasing magnetic field. Their ranges and stabilities are found to depend on dot size ratios and to increase with P.
