We calculate the exciation frequencies of m=0 mode and m=2 mode of Rb87 atoms confined in an anisotropic trap and interacting with repulsive forces by diffusion Monte Carlo method. The spectrum turns out to be strongly temperature dependent and we compare our results with other theories and experiments. This is the first Monte Carlo calculation for a trapped Bose Einstein condensed dilute gas w...

We present a relatively simple method for efficiently transforming a single high-order mode into a nearly Gaussian beam of much higher quality. The method is based on dividing the mode into equal parts that are then combined coherently. We illustrate the method by transforming a Hermite-Gaussian (1, 0) mode with M(x)(2)=3 into a nearly Gaussian beam with M(x)(2)=1. 045 . Experimental results ar...

We consider the problem of building an arbitrary N × N real orthogonal operator using a finite set, S, of elementary quantum optics gates operating on m ≤ N modes the problem of universality of S on N modes. In particular, we focus on the universality problem of an m-mode beamsplitter. Using methods of control theory and some properties of rotations in three dimensions, we prove that any nontri...

Of 89 patients with idiopathic hypertrophic subaortic stenosis who had M-mode echocardiagrams recorded, seven patients with coexisting moderate to large pericardial effusions were identified. The clinical profile, M-mode echocardiograms, and cardiac catheterization and angiocardiographic studies in two of the seven patients were analyzed. That the two entities were not associated was suggested ...

The mode of coordination of8 manganese(fI), cobaltm, nickel(H), copper(II), zinc(H), lead(II) and cadmium(I1) to sodium ascorbate (NaHAsc) was investigated using IR, UV-visible, AAS, elemental microanalyzer, conductivity, magnetic and 'M and I3C NMR spectroscopic studies, NaNAsc is bidentate and coordination was through the carbonyl group and the oxygen atom of carbon-2 enolic hydfoxyl grou...

We compute an array of Standard Model Higgs boson (H) signals and backgrounds for a possible upgrade of the Tevatron to √ s = 4 TeV. Taking m t ≥ 140 GeV, and assuming a total accumulated luminosity of L = 30 fb −1 , we find that a Standard Model Higgs boson with m H < ∼ 110 GeV could almost certainly be detected using the W ± H → lνbb mode. A Higgs boson with mass between ∼ 120 GeV and ∼ 140 G...

We propose entangled (M+1)-mode quantum states as a multiuser quantum channel for continuous-variable communication. Arbitrary quantum states can be sent via this channel simultaneously to M remote and separated locations with equal minimum excess noise in each output mode. For a set of coherent-state inputs, the channel realizes optimal symmetric 1-->M cloning at a distance ("telecloning"). It...

Full characterization of fullerenol C60(OH)24 by HPLC ESI-MS in negative and positive ionization modes was achieved. Fragmentor voltage and capillary voltage were optimized in order to obtain a good signal stability and the best peak intensity distribution for the fullerenol C60(OH)24 in both negative and positive modes. While the predominant base peak observed for C60(OH)24 in the negative ion...

We develop a novel method of creating optical vortex array by the conversion of a standing-wave Laguerre-Gaussian (LG) mode. Theoretically, by employing the transformational relation, the standing-wave LG mode is verified to be transformed from a pair of crisscrossed Hermite-Gaussian (HG) modes, embedded with optical vortex array, consists of a TEMn,m mode and a TEMm,n mod...
