We make a detailed analysis of the $BB\rho(DD\rho)$ and $B^*B\rho(D^{*}D\rho)$ strong couplings $g_{BB\rho}(g_{DD\rho})$ and $g_{B^*B\rho}(g_{D^{*}D\rho})$ using QCD light cone sum rules(LCSR). The existing some negligence is pointed out in the previ

In this letter, we have studied the influence of the external magnetic fields on tunneling of the spin-1 Bose condensate. We find that the population transfer between spin-0 and spin-?1 exhibits the step structure under the external cosinusoidal magn

A new kind of k-quantum nonlinear coherent states, i.e., the k eigenstates of the k-th power B-k (k greater than or equal to 3) of the generalized annihilation operator B = a1/f(N) of f-oscillators, are obtained and their properties are discussed. Th

Interference of an atomic Bose–Einstein condensate interacting with a laser field in a double-well potential with dissipation is investigated. If properly selecting the laser field and the initial states of the atoms in the two wells, we find that

In this paper, we study quadrature squeezings of two Bose–Einstein condensates with collision and nonclassical properties of pair entanglement in four wave mixing in Bose–Einstein condensates. With the aid of a numerical method, we find that the

Within the framework of slave-boson mean-field theory, we study the thermodynamic properties of the periodic Anderson lattice model with half-filled conduction band and one 4f electron at each primitive cell and the degeneracy . It is found that afte

By using the well known slave-boson technique and within the framework of mean field approximation, we study the effect of the direct f-f hopping on the low-temperature hybridization gap insulating behavior of the periodic Anderson lattice. The resul

We have studied the properties of the amplitude-N-th powered squeezing of an electromagnetic field in the k-photon Jaynes-Cummings model of an atom initially being in the ground state and coupling with the superposition state. The results show that,

Using numerical calculation method, we have studied the Anderson transition in the Soukoulis-Economou model of one-dimensional incommensurate systems. Our results indicate that the Anderson transition in this model should take place gradually, i.e.,

We study few-electron semiconductor quantum dots using the unrestricted Hartree-Fock-Roothaan method based on the Gaussian basis. Our emphasis is on the energy level calculation for quantum dots. The confinement potential in a quantum dot is assumed
