We describe hidden symmetry and its application to the construction of exact correlated states of electrons and holes in quantum dots. The hidden symmetry is related to degenerate single particle energy shells and symmetric interactions. Both can be engineered in a quantum dot. We focus on hidden sy
The states of two electrons in a semiconducting nanotube dot are computed by exact diagonalisation of a 2-band effective mass Hamiltonian and compared to the states obtained from a molecular model. The molecular model is found to be accurate for the ground and excited states in a wide range of nanot
