In an open V-type system,by numerical results of differential equations,the physical mechanism of laser without inversion(LWI)was analyzed,and the effects of the probe and driving fields detunings,the Rabi frequencies of the driving fields,and the initial values of the populations on LWI transient were discussed. The cIn an open V-type system,by numerical results of differential equations,the physical mechanism of laser without inversion(LWI)was analyzed,and the effects of the probe and driving fields detunings,the Rabi frequencies of the driving fields,and the initial values of the populations on LWI transient were discussed. The conclusions show that the populations of the two levels coupled by the driving field have the same oscillation frequency,however,exist a phase difference π.The dispersion equals to zero and twophoton coherent item is real number when the driving and the probe fields are both resonant. Oscillation period of the gain,coherent item and population difference reduce with the increase of the Rabi frequencies of the driving field. The initial values of the populations mainly affect the oscillation amplitudes of the gain,coherent item and population difference but don't affect their values in the steady state..

Excited state population distribution of 5S1/2 →5P3/2 with laser excitation in room temperature rubidium vapor mixed with H2 was quantitatively analyzed by absorption and saturation spectroscopy.When the laser linewidth is much smaller than the Doppler linewidth,the absorption coefficients were measured for a series ofExcited state population distribution of 5S1/2 →5P3/2 with laser excitation in room temperature rubidium vapor mixed with H2 was quantitatively analyzed by absorption and saturation spectroscopy.When the laser linewidth is much smaller than the Doppler linewidth,the absorption coefficients were measured for a series of laser powers between 40 μW and 5 mW at 780 nm. Population in the 5P3/2 level obtained from the saturation measurements was also determined by the absorption measurement of narrow spectral line from a Rb hollow cathode lamp. The results obtained in these two ways arin good agreement.When the H2 pressure was 100 Pa,it was shown that 8% of the ground state population could be transferred to the first excited state by pumping the Doppler broadened line with a single-mode narrow-band laser..

Based on the singlecoin-tossing game studied by Meyer,the dice game which has six states is discussed. In classical dice game,the probabilities of two players,P and Q,to win the game are both equal to 1/2.In quantum dice game,each state of the dice can be denoted by its density matrix. And if the player Q adopts quantum strategies instead of classical ones while the other player P adopts the usual classical probabilistic strategies,Q can control this game completely. It can be concluded that for dice game,quantum strategies are more successful than classical ones..

In order to explore the mechanism of mode-selective excitation The selective excitation of coherent anti-Stokes Raman scattering(CARS)to the νs(CH3)(2832 cm-1)and the νAS(CH3)(2948 cm-1 )vibrational modes from methanol solution is successfully achieved by adaptive femtosecond pulse shaping coherent control technology. In order to explore the mechanism of mode-selective excitation from two-pulse femtosecond CARS spectrum,second harmonic generation frequency-resolved optical gating(SHG-FROG)method is used to measure the original and optimal pump pulses. SHG-FROG traces indicate that the mode-selective excitation of femtosecond CARS spectrum can be achieved by manipulating the effective frequency components of the pump pulse related to specific molecular vibrational mode. The experimental results demonstrate that adaptive femtosecond pulse shaping coherent control technology has scientific significance for the complicated molecular systems..

Li-hu TENG, Wei ZHOU, Bao-ying FENG, Xiao-juan OU, and Wei-hua ZOU
The characteristics of signal transmission speed in the condition of superluminal group velocity are discussed. When an amplitude modulated sinusoid signal is sent into mismatched transmission line groups at some special carrier frequencies,its group velocity of envelope is superluminal. The speed fluctuation accordingThe characteristics of signal transmission speed in the condition of superluminal group velocity are discussed. When an amplitude modulated sinusoid signal is sent into mismatched transmission line groups at some special carrier frequencies,its group velocity of envelope is superluminal. The speed fluctuation according to the length changes of the line is verified. The group velocity of the signal envelope in the forbidden band is one to two times faster than the speed of light(c)in vacuum. Even negative group velocity occurs when the total length of the mismatched line group is long enough such as 179.8 m. According to the experiment,differences between superluminal group velocity in certain condition and the light speed in general propagation exist in not only the speed values but also the speed fluctuations. The experimental result reveals that the characteristic of superluminal group velocity propagation speed is obviously different from that of electricity and light in normal propagation..

The existence of magnetic fields can obviously reduce the entanglement,and it is found that the critical temperature depends on the anisotropic parameter The thermal entanglement of spin-1 XXZ-type Heisenberg chains in the presence of a uniform magnetic field along z axes is investigated by means of negativity theory. The existence of magnetic fields can obviously reduce the entanglement,and it is found that the critical temperature depends on the anisotropic parameter Δ but not on the uniform magnetic field. The results show that the increase of the qutrit results in the decrease of the critical temperature. In addition,the critical temperature is independent of the lengthof the chain..

Using the numerical method,the influences The entanglement time evolution of Tavis-Cummings model with Gaussian coupling is investigated. The entanglement between coherent field and two atoms is explored by using the quantum reduced entropy,and the entanglement between two atoms is studied by using Negativity entropy. Using the numerical method,the influences of the atomic motion perpendicularity to the axes of resonant cavity and initial states of the system on the entanglement are discussed. The results indicate that the time evolutions of the two entanglements are similar. But at the same time the stronger the entanglement between field and two atoms is,the weaker that between the two atoms is. The motion affects the entanglement. When the mean photon number increases,the Rabi frequency increases while the vibration amplitude decreases. When the atomic initial state changes,the entanglement appears similar time evolution..

The influences of the initial states of the Λ-type three-level atom and the parameter of the binomial optical fields on squeezing of the optical field and the second-order coherence degree are investigated in detail. As the detuning parameter of atom Δ and the parameter of the binomial optical field η are small,bunching and antibunching effect can be exhibited alternatively. With the increase of the parameters,the light field shows antibunching effect completely. If the detuning parameter of atom Δ and the parameter η are chosen appropriately,the component X1 of the light field in the coupling system will be squeezed during the certain time. The results indicate that the light field shows squeezing effects and continuous antibunching effect under a certain condition as it interactes with a Λ-type three-level atom..

Xia TAN, and Cheng-qiang ZHANG
The quantum statistical properties in the system of a two-mode SU(1,1)coherent field interacting with a two-level atom are investigated by solving Milburn equation. The effects on the quantum statistical properties induced by the intrinsic decoherence,the two-mode photon number and the mean photon number are analyzed. The quantum statistical properties in the system of a two-mode SU(1,1)coherent field interacting with a two-level atom are investigated by solving Milburn equation. The effects on the quantum statistical properties induced by the intrinsic decoherence,the two-mode photon number and the mean photon number are analyzed. The results show that the intrinsic decoherence strengthens the anti-bunching effect of the two-mode and the correlation intensity between the two modes and makes the first mode of the field always to be sub-Poissonian. The second-order coherence degree of the two-mode field also exhibits obvious collapserevival effect with the intrinsic decoherence. The first mode of the field is sub-Poissonian with the evolution of the time. The photon anti-bunching appears and the correlation between the two modes of light is both positive and non-classical. But in most of the time,the second mode of the field is Poissonian with the evolution of the time and the photon bunching appears..

The results show that near the ideal first-order soliton,the scattering can make the smallest soliton squeezed ratio with the increase of the soliton pulse amplitude,that is to say the larger soliton squeezed state can be gotten. With the increase of the loss,the squeezed degree of the squeezed state slowly decreases. When the loss is same,the transmission distance to get the smallest soliton squeezed ratio is shorter than that before the scattering with the increase of the soliton pulse amplitude..
