## Abstract We have developed a variational manyβbody description for fewβelectron 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
We report on the basic properties of recently observed magnetic field resonance, induced time-dependent oscillation, and hysteresis effects in the current flowing through two weakly coupled vertical quantum dots at high source-drain bias (up to a few tens of mV). These effects bare some similarity t
