对Huang,Wu and Florin,“评论非保守光学力的影响.”(arxiv:0806.4632)
Response to Huang, Wu and Florin, "Comment on Influence of non-conservative optical forces ..." (arxiv:0806.4632)
摘要:
最近,Huang,Wu和Florin在我们的预印本(0804.0730v1)上发表了一篇评论(0806.4632v1),描述了被光镊捕获的胶体球的非平衡循环。该评论建议,从原始帖子中的实验和模拟中获得的环形概率流的证据应被视为非决定性的。作者的担忧基于两个声明:(1)被困粒子运动的布朗动力学模拟显示没有统计学意义的环流,(2)作用在被困球体上的辐射压力的现实描述与我们描述的运动不一致。在本回复中,我们证明这两个声明都是不正确的,因此0804.0730v1中的原始结果和结论仍然有效。
英文摘要:
Recently, Huang, Wu and Florin posted a Comment (0806.4632v1) on our preprint (0804.0730v1) describing nonequilibrium circulation of a colloidal sphere trapped in a optical tweezer. The Comment suggests that evidence for toroidal probability currents obtained from experiments and simulations in the original posting should be considered inconclusive. The authors' concerns are based on two claims: (1) that Brownian dynamics simulations of the trapped particle's motions reveal no statistically significant circulation, and (2) that a realistic description of the radiation pressure acting on the trapped sphere is inconsistent with the motion we have described. In this Reply, we demonstrate both of these claims to be incorrect, and thus the original results and conclusions in 0804.0730v1 to be still valid.
