The energy spectra of the ground state for an exciton (X) trapped by a neutral acceptor (A^o) in a quantumdot with a parabolic confinement have been calculated
The generalized one-dimensional Fokker-Planck equation is analyzed via potential symmetry method and the invariant solutions under potential symmetries are obta
Using two Einstein-Podolsky Rosen pair eigenstates |η) as quantum channels, we study the teleportationof two-mode quantum state of continuous variables.
