## Abstract We have developed a variational manyโbody description for fewโelectron systems in a parabolic quantum dot in an external magnetic field. The ground state energy of the electronic system has been theoretically investigated in a broad range of magnetic fields. The possibility of existence
Exact-diagonalization studies of few-electron quantum dots and disks are performed, with the aim to investigate a Wigner cluster-Fermi liquid crossover in zero magnetic รฟeld at varying strength of Coulomb interaction. A clear indication of a transition of a liquid-solid type in the ground state is f
