The dark spatial soliton interaction in nonlinear Kerr medium has been studied in this paper. The problem has been solved by the use of the slowly varyingenvelope approximation in solving coupled nonlinear Schrodinger equations. The perturbation nature of dark spatial soliton interaction has been described and some of their key properties has been discussed as well in the paper.

The modified Chaplygin gas (MCG) as an interacting model of holographic dark energy in which dark energy and dark matter are coupled together is investigated in this paper. Concretely, by studying the evolutions of related cosmological quantities such as density parameter Ω, equation of state w, deceleration parameter q and transition redshift zT, we find the evolution of the universe is from deceleration to acceleration, their present values are consistent with the latest observations, and the equation of state of holographic dark energy can cross the phantom divide w = -1. Furthermore, we put emphasis upon the geometrical diagnostics for our model, i.e., the statefinder and Om diagnostics. By illustrating the evolutionary trajectories in r - s, r - q, w -w and Om planes, we find that the holographic constant c and the coupling constant b play very important roles in the holographic dark energy (HDE) model. In addition, we also plot the LCDM horizontal lines in Om diagrams, and show the discrimination between the HDE and LCDM models.

The effect of the dielectric mismatch between the well and the barrier materials on the binding energies of shallow donor has been investigated in Inx Ga1-xAs/GaAsstrained quantum well. The binding energies as a function of the well widths and impurity positions in the well and the barriers are obtained by using a variational method. Calculation results show that the effect of the dielectric mismatch is quite sizable and such effect is larger for off-center impurity positions,but the effect of the lattice mismatch is small in general.

By using the home-made femtosecond laser system and the time-of-flight mass spectrometer, the decay dynamics of excited carbon disulfide (CS2) and ammonia (NH3) are investigated in real time by pump-probe mul-tiphoton ionization detection. The estimated lifetime constantof the NH3 A1A2 state (51±4 fs) agreed quite well with the literature report. For the first time, the decay lifetime constants of the NH3 E’1A’1, state (937±93 fs), the CS2 a3A2 state (153±10 fs), and the CS2 Rydberg state[3/2](3IIg) (948±23 fs) are obtained.

The new particles predicted by the littlest Higgs model with T-parity (called LHT model) can induce the lepton flavor violation (LFV) couplings at the one-loop level,which can add contributions to some LFV *** into account the constraints of the experimental data on the relevant free parameters,we calculate the branching ratios of the LFV decay processes Z → l ˉl and τ-→μ-P 1 P 2 with P 1 P 2 = π + π-,K + K-,and K0 ˉK 0 in the context of this new physics *** find that the LHT model can indeed make significant contributions to some of these LFV decay *** Z factory option for the future high energy e + e-collider experiments will give severe constraints on the LHT model.

In the context of the littlest Higgs (LH) model, we estimatc the production cross section of the process e~-γ→e~-H in the future high-energy linear e~+e~- collider (IL C) with the center-of-mass (CM) energy S=500 *** numerical results show that the contributions of the LH model to this process are very small in most of the parameter space allowed by the electroweak precision measurement data, and are very difficult to be detected in the future ILC experiments.
