	Abstract:Fully differential cross sections of single ionization of Ne atom by a 36.1 eV linearly polarized XUV (attosecond extreme ultraviolet) photon has been studied using a reaction microscope. We obtain photoelectron angular distribution and β-asymmetry parameter directly. The measured angular distribution and β-asymmetry parameter are in a good agreement with the previous experimental results and the most accurate theoretical calculation.

	Abstract:GaFeO3 bulks with x from 0.7 to 1.3 have been fabricated by using classic solid-state route. The structural, optical, and magnetic properties have been investigated systematically. The results of EDX demonstrated that the Fe content can be obtained by adjusting the Fe content in the powders. XRD spectra and FULLPROF profile fitting indicated that GFO bulks belong to the orthorhombic structure with space group Pc21n. Phase separation appeared at the Fe content of x=1.3. Meanwhile, the magnetic property measurements suggested that GaFeO3 is ferromagnetic, and magnetic properties can be enhanced by increasing the Fe content, which is of vital importance for the application of ferromagnetic semiconductors.

	Abstract:In this paper, we present high resolution photoassociation spectroscopy of NaCs molecules in long-range state below the Na (3S1/2) + Cs (6P3/2) asymptote. The excited state NaCs molecules are produced by photoassociation of ultracold Na and Cs atoms in a dual-species magneto-optical trap. Trap loss spectroscopy of the ultracold polar NaCs molecules formed by photoassociation, has been experimentally obtained by using highly sensitive modulation spectroscopy technique. PA spectrocopy for c3Σ+ state correlated to Na (3S1/2) + Cs (6P3/2) asymptote is demonstrated and the binding energies of the molecular levels are provided.

	Abstract:We report a method of high-sensitively detecting the weak signal in photoassociation (PA) spectra of ultracold NaCs molecules by phase sensitive-demodulated trap-loss spectra of Na atoms from a photomultiplier tube. We found that the signal-to-noise ratio (SNR) of the PA spectra is strongly dependent on the integration time and the sensitivity of the lock-in amplifier, and our results show reasonable agreement with the theoretical analyses of the SNR with the demodulation parameters. Meanwhile, we investigate the effect of the interaction time of PA laser with the colliding Na-Cs atom pairs on the SNR of PA spectra. The dynamical process of the atom loss rate is dependent on both the PA induced atom loss and the loading of the MOT. The high-sensitive detection of the excited ultracold NaCs molecules lays a solid foundation for further study of the formation and application of ultracold NaCs molecules.

	Abstract:It has been studied the spectroscopy of a simple two-level single molecule coupled to a nonequilibrium environment,driven by an external classical laser field based on the generating function approach.The environmental nonequilibrium feature is characterized by a non-Markovian environmental noise process with nonstationary statistical properties.In the situation when the environmental noise is memoryless, the statistical properties related to photon emission of the system such as the average photon number, the line shape, the Mandel $Q$ parameter and so on can be obtained, and then the phenomenon in spectral dynamics induced by the environmental nonequilibrium feature can be observed.}%It is shown that the spectral narrowing phenomenon was observed when the system dynamics transits from non-Markovian to Markovian due to the decrease of the coupling between the system and the environment.

	Abstract:With trajectory surface-hopping dynamics at the semi-empirical OM2/MRCIlevel, photoisomerization dynamics of a light-driven molecular rotary motor is investigated in gas phase. A meanlifetime of the S$_{1}$ excited state for the M structure (see Figure 1 in the text) is about 580 fs in gas phase.The dynamical process of electronic de-excitation is followed by the twisting about the centralC=C double bond and the out of plane motion of pyramidalization. Two S$_{1}$/S$_{0}$ conical intersections (CI) are found, and de-excitation from the S$_{1}$ excited state occurs at these two CI. Since the difference betweenthe energy barriers on these two routines, the de-excitation mainly occurs at one CI named as CI$_{1}$.The quantum yield of the M-P photoisomerization of this molecular motor is about 63.6% in our calculation.Although the averaged lifetime of the M structure was close to 600 fs, our calculated fluorescence emission spectrum shown that the fluorescence emission nearly disappeared after 100 fs, which means that most of molecules arrived at ``dark state" after 100 fs. Our calculatation result about fluorescence emission spectrum agrees well with the experimental result of Feringa et al.

	7. The quantum measurement of the two-qubit system in damping noise environment

	Abstract:It's known that the inevitable interaction of the entangled qubits with their environments may result in the degradation of quantum correlation. We study the decoherence of two remote qubits under general local single- and two-sided amplitude-damping channel(ADC). By using concurrence, quantum discord and Clauser-Horne-Shimony-Holt (CHSH) inequality, we find that the relation between the residual quantum correlations and the initial ones are different. Recently, Wang et al. showed that there exist a set of partially entangled states that are more robust than maximally entangled states in terms of the residual quantum correlation measured by concurrence, fully entangled fraction and quantum discord, respectively. Here we find that both in single- and two-sided ADC, only the evolution of CHSH inequality with the initial parameter is proportional to that of the initial nonloality. That means the initial state with maximally nonlocality will retain its role in the evolution. It implies that the evolution of nonlocality may reveal the characteristics of quantum state better. Furthermore, we discuss the evolutions of the three different quantum measurements with the initial parameter under generalized amplitude damping channel(GADC) and find that they are all proportional to that of the initial state.

	8. Improving entanglement of two atoms in strong coupling regime

	Abstract:We consider a model of two identical atoms coupled to a single-mode cavity. When in atom-field strong coupling regime, the entanglement of the two atoms with spontaneous emission should be investigated beyond rotating-wave approximation. In order to improve the entanglement of the two atoms, some typical feedbacks based on quantum jump are attempted to impose on the atoms. The result of numerical simulations shows that an appropriate feedback control can improve the entanglement.

	9. Non-Markovian Transfer Tensor Method Used in a Chemical Reaction in Liquid

	Abstract:In this paper, the non-Markovian transfer tensor method (TTM) suggested by Cao's group was utilized in a real chemical reaction in liquids from a classical point of view. From the results of this numerical simulation, dramatic enhancement in speed of calculations and decrease in computational cost are shown by applying TTM method. It is wise to be used in complex systems with lots of degrees, such as the process of protein folding or in treating propagations with mountains of data. For some speci_c quantities we are interested in, how to _nd a map from complex systems to simple ones and from huge freedoms to a few ones, such as just to one freedom in this paper, it remains something for us to do in the future.

	10. Effects of initial rotational quantum state excitations and thermal rate coefficients at room temperature for H + NH -> N + HH reaction

	Abstract:In this paper, a full quantum mechanical (QM) wave-packet m- ethod was used to study the effects of initial rotational quan- tum state excitations including non-zero total angular mo- menta for the H(2S)+NH(X3Σ-)→N(4S) + H2(X1Σg+) reaction system. Initial-state-specific reaction probabilities (RPs), integral cross sections (ICSs) and rate constants (RCs) averaged over all k states considered for rotational quantum number j from 0 to 6 are given, where k is the projection of diatomic rotational angular momentum onto the body fixed z axis. In general, rotational excitations enhance the reactivity comparing with that of the ground state in high energy region, while it depends on the initial states in low energy re- gion. At room temperature, the thermal RC averaged over 7 rotational states is slightly larger than that of the experimen- tal measurement. However, if more initial rotational states are taken into account, the agreement will be bettert.
