Laser induced emission of the fully correlated electron pair from a quantum dot. — •Oleg Kidun and Dieter Bauer — Max-Planck-Institut fuer Kernphysik, Heidelberg,

The exactly solvable problems of two electrons coupled by the Coulomb interaction can be used as unique tests for any approximate theory that deals with few-body systems and related experiments [1,2]. We use the two-electron states of the parabolic potential well and the two-electron states in a strong electromagnetic field to calculate the time evolution of the emission probability of electron pairs. As an example, we compare the sequential double ionization, which is the conventional one-particle description of multielectron ejection, and the solution based on two-electron correlated states [3]. The entanglement and the conditions of separability of these correlated states are discussed.
