We construct the nonlinear tripartite entangled state representation and the related generalized Wigner operator. Then we discussed the Wigner functions of the
Starting from the known variable separation excitations of a(2 + 1)-dimensional generalized Ablowitz-Kaup-Newell-Segur system,rich coherent structures can be de
By means of both the theory for pressure-induced shifts (PS) of energy spectra and the theory for shiftsof energy spectra due to electron-phonon interaction (EP
With the use of variational method to solve the effective mass equation, we have studied the electronic and shallow impurity states in semiconductor heterostruc
A system of three charged bosons confined in a harmonic trap has been investigated by an exact diagonalization. We report a calculation for the energy spectrum
A transformation is introduced and applied to solve Burgers-type equations,such as Burgers equation,Burgers-KdV equation and Burgers-KdV-Kuramoto equation.Many
