1.The group's activities in this area have concentrated on the mechanical

effects of angular momentum on a dielectric and on the quantum properties of orbital angular momentum.

在这个研究领域,这个研究组主要集中在电介质中的角动量的机械效应和轨道角动量的量子属性。

 

2.    Experimental realization of entanglement have been restricted to

two-state quantum systems. In this experiment entanglement exploiting the orbital angular momentum of photons, which are states of the electromagnetic field with phase singularities (doughnut modes).

纠缠的实验认识还只停留在二维量子系统。在这实验中,利用了光子的轨道角动量的纠缠是具有相位奇点(暗中空模式)的电磁场的状态。

 

3. Laguerre Gaussian modes with an index l carry an orbital angular momentum of  per photon for linearly polarized light that is distinct from the angular momentum of the photons associated with their polarization

对线偏振光来说,具有因子l的LG模式的每个光子能携带 的轨道角动量,这是与偏振态相关的光子的角动量是截然不同的。

 

4. This opens up a practical approach to multi-dimensional entanglement where the entangled states do not only consist of two orthogonal states but of many of them. We expect such states to be of importance for the current efforts in the field of quantum computation and quantum communication.

它打开了一条通往多维纠缠态切实可行的通道,这纠缠态不仅存在于二维正交态中而且存在于多维正交态中。我们预料这纠缠态对于我们在量子计算和量子通信这个领域的努力是极其重要的

 

5. Given the experimental verification of the {orbital angular momentum conservation} one may expect to find entanglement between the two photons produced in the conversion process. Further experimental results show that the two-photon state goes beyond classical correlation and indeed we were able to prove the entanglement for photon states with phase singularities.

轨道角动量转换这个实验确认,人们可能发现纠缠存在于转换过程中的被诱导的两个光子中.进一步实验结果确认这两个光子的状态可能不存在经典的联系,我们确实能够证明具有相位奇点光子状态的纠缠。

 

6. The wave front (top) and the intensity pattern (bottom) of the simplest Laguerre Gauss ( ) or doughnut mode. The index l is referred to as the winding number and (p+1) is the number of radial nodes. The customary Gaussian mode can be viewed as LG mode with l=0.

最基本的LG( )和暗中空模式的波前(上)和强度图形(下)。L是径向回转数,p+1是径向波节数。普通的LG模可看作l=0的LG模。

 

7. The handedness of the helical wave fronts of the LG modes is linked to the sign of the index l and can be chosen by convention. The azimuthal phase term of the LG modes results in helical wave fronts. The phase variation along a closed path around the beam center is .

LG模的螺旋波前的左右手习惯是和l的特征相联系的,能够按规定进行选择。LG模的角向术语 来源于螺旋波前,相变量沿着一条封闭路径绕光束中心一周就 .

 

8. "Optical vortices" might extract abundant information from matter, providing a new and potentially wide-ranging optical tool, a Spain-US team has proposed theoretically.

一个西班牙和美国团队从理论上提出,“光涡旋”可能从物质获得大量信息,从而提出了一个新的,潜在的广泛应用的光学工具。

 

9. An ordinary light beam, when viewed head-on, looks like a bright circle. But a special light beam called an "optical vortex," when viewed head-on, looks like a bright ring surrounding a dark central core,Optical vortices are the simplest kind of beam carrying a property called "orbital angular momentum".

一束普通的光,当我们迎面看时,就像一束明亮的圆周,但对于一束特殊的称作“光涡旋“的光束,我们迎面看时,像一个明亮的环绕着一个黑暗的圆心,这种光具有“轨道角动量”的属性,光涡旋是其中最简单的一种。

 

10. However, for light with orbital angular momentum (OAM), the energy spirals around the beam axis. Ordinary beams carry only "spin angular momentum," encoded in the polarization of light.

然而,对于具有轨道角动量(OAM)的光,其能量绕着光轴螺旋,普通的光仅仅携带“自旋角动量”,用光的偏振态进行编码。

 

11. All possible spin states can be constructed with just two polarization states (vertical and horizontal, or clockwise and counterclockwise).

所有的自旋状态都能用两个偏振态进行构建(垂直和水平,或者顺时针和逆时针)。

 

12.Around the dark core of an optical vortex, the energy flow carried by the light beam is like a spiral staircase, flowing in a clockwise or counterclockwise direction.

绕着光涡旋的黑暗中心,光束携带的能量流就像螺旋梯,沿着顺时针或者逆时针方向流动。

 

13. How an optical vortex reverses its spin: The laser beam propagates in the horizontal (z) direction and the transverse (x-y) plane is the cross-section of the beam at a given z-plane.

光涡旋怎样倒转它的自旋:在一个给定的z平面,激光沿水平z方向和横向的(x-y)平面的传播是光束的截面。

 

14. Mechanical properties of light like linear and angular momentum allow for the trapping, rotation and manipulation of microscopic objects.

线动量和角动量的机械特性有诱捕,旋转和对细微颗粒的操作。

 

15. A recent experiment shows that both the spin and the orbital angular momentum transferred to a small particle held off-axis are proportional to the local intensity of the beam .

最近的实验表明,传给远轴的小颗粒的自旋和轨道角动量是与光束的局部光强成比例。
