We study the time evolution of quantum discord and entanglement of a two-qubit system in thermal reservoirs. We find that there are no simple ordering relations between entanglement and quantum discord for the dynamical evolution behavior; that is, quantum discord may be smaller or larger than entanglement in the evolution process. However, a strong correlation between changes of the ordering relations and the mean photon number is found. In addition, it also shows that entanglement is not the strongest form of nonclassicality.
研究了热储中双量子比特系统的量子不和谐和纠缠的时间演化。我们发现量子纠缠和量子不和谐在动力学演化行为中不存在简单的有序关系;也就是说,在进化过程中,量子不和谐可能比纠缠更小或更大。然而,序关系的变化与平均光子数之间有很强的相关性。此外,它还表明纠缠不是非经典性的最强形式。

FTIR spectra of acetone-chloroform system with various component ratios were investigated within the spectral range 3950–4550 cm−1. Methods of multivariate curve resolution were applied to decompose the FTIR spectra into specific components of different composition. A method of decomposition based on structural model of solution which contains acetone, chloroform, and complex acetone/chloroform (1 : 1) was proposed. Results of both approaches are in good agreement within the range of measuring error.

Spatial variation in intensity of spectral emission, electron temperature, number density, and the time of flight (TOF) of ions and neutrals at various oxygen ambiances has been investigated on ferroelectric lead zirconium titanate (PZT) plasma using optical emission spectroscopy. Plasma produced by ablating PZT ceramic target using Nd-YAG laser operating at the third harmonics ( nm,  ns, repetition frequency 10 Hz) was investigated at various oxygen partial pressures and at various distances from the target surface. Here energy density for laser fluence was fixed as 3.13 Jcm−2 and distance from the target and ambient gas pressure were varied. The electron number density and electron temperature of the PZT plasma at the early stage of plume expansion were measured as  Jcm−2 and 13200 K, respectively, and thus verified the existence of local thermodynamic equilibrium (LTE). Time of flight spectra (TOF) of neutral and singly ionized species in plasma were recorded. The result shows that plasma parameters and velocity of species are of same order for various oxygen partial pressures but have a decreasing tendency with distance. The energy of almost all species in the plume become more or less same at 0.1 mbar. These conditions favour the growth of perovskite PZT thin films.
利用光学发射光谱研究了钛酸铅锆(PZT)等离子体在不同氧环境下离子和中性离子的光谱发射强度、电子温度、数密度和飞行时间(TOF)的空间变化。研究了三次谐波(nm, ns,重复频率10 Hz) Nd-YAG激光在不同氧分压和距离靶表面不同距离下烧蚀PZT陶瓷靶产生的等离子体。在这里,激光能量密度固定为3.13 Jcm−2,并改变与目标的距离和环境气体压力。在羽流膨胀初期,PZT等离子体的电子数密度和电子温度分别为Jcm−2和13200 K,从而验证了局域热力学平衡(LTE)的存在。记录了等离子体中中性和单电离物质的飞行时间光谱(TOF)。结果表明:在不同的氧分压下,等离子体参数和粒子速度都是同数量级的,但随着距离的增加有减小的趋势。在0.1毫巴时,羽流中几乎所有物质的能量都差不多了。这些条件有利于钙钛矿PZT薄膜的生长。

We have calculated forbidden transitions (M1 and E2) between fine structure levels in the ground state configuration 3s23p4 of doubly ionized argon (Ar III) using the multiconfiguration Hartree-Fock approach within the framework of the Breit-Pauli Hamiltonian. The data for the analysis of forbidden lines in the spectrum is important for the study of the plasma in astrophysical objects and fusion devices. The results obtained from this work have been compared with other results available in the literature.

Solutions to the Schrödinger Equation with Inversely Quadratic Yukawa Plus Inversely Quadratic Hellmann Potential Using Nikiforov-Uvarov Method 用Nikiforov-Uvarov方法求解逆二次Yukawa和逆二次Hellmann势Schrödinger方程
Pub Date : 2013-12-09 DOI: 10.1155/2013/582610

The solutions to the Schrodinger equation with inversely quadratic Yukawa and inversely quadratic Hellmann (IQYIQH) potential for any angular momentum quantum number have been presented using the Nikiforov-Uvarov method. The bound state energy eigenvalues and the corresponding unnormalized eigenfunctions are obtained in terms of the Laguerre polynomials. The NU method is related to the solutions in terms of generalized Jacobi polynomials. In the NU method, the Schrodinger equation is reduced to a generalized equation of hypergeometric type using the coordinate transformation . The equation then yields a form whose polynomial solutions are given by the well-known Rodrigues relation. With the introduction of the IQYIQH potential into the Schrodinger equation, the resultant equation is further transformed in such a way that certain polynomials with four different possible forms are obtained. Out of these forms, only one form is suitable for use in obtaining the energy eigenvalues and the corresponding eigenfunctions of the Schrodinger equation.
利用Nikiforov-Uvarov方法,给出了任意角动量量子数具有逆二次Yukawa势和逆二次Hellmann势的薛定谔方程的解。利用拉盖尔多项式得到了束缚态能量特征值和相应的非归一化特征函数。NU方法与广义雅可比多项式的解有关。在NU方法中,利用坐标变换将薛定谔方程化为超几何型的广义方程。然后,该方程产生一种形式,其多项式解由著名的罗德里格斯关系给出。将IQYIQH势引入薛定谔方程后,得到的结果方程进一步变换,得到了具有四种不同可能形式的多项式。在这些形式中,只有一种形式适合用于获得薛定谔方程的能量特征值和相应的特征函数。

This paper presents the MPI parallelization of a new algorithm—DPD-B thermostat—for molecular dynamics simulations. The presented results are using Martini Coarse Grained Water System. It should be taken into account that molecular dynamics simulations are time consuming. In some cases the running time varies from days to weeks and even months. Therefore, parallelization is one solution for reducing the execution time. The paper describes the new algorithm, the main characteristics of the MPI parallelization of the new algorithm, and the simulation performances.

Multispark discharge excited in water is described, and its useful physical and chemical properties are discussed in the light of some environmental issues. Discharge of such a type generates hot and dense plasmoids producing intense biologically active UV radiation and chemically active radicals, atoms, and molecules. Simultaneously, discharge creates strong hydrodynamic perturbations and cavitation bubbles. Particular attention is given to factors influencing on water purity with special reference to discharge application for effective sterilization of water and its cleaning of harmful chemicals. The gas discharges of this type show considerable promise as a means for solving some actual plasma-chemical problems. The above-mentioned discharge properties have been demonstrated in a series of laboratory experiments, which proved the efficiency of disinfection of potable and waste water, water cleaning of pesticide (herbicide) contaminations, and conversion (recovery) of natural methane.
介绍了水中激发的多火花放电,并结合一些环境问题讨论了其有用的物理和化学性质。这种类型的放电产生热而致密的等离子体,产生强烈的生物活性紫外线辐射和化学活性自由基、原子和分子。同时,放电产生强烈的流体动力扰动和空化气泡。特别注意影响水纯度的因素,特别提到水的有效灭菌和有害化学物质的清洗的排放应用。这种类型的气体放电作为解决一些实际等离子体化学问题的一种手段显示出相当大的希望。上述排放特性已在一系列实验室实验中得到证实,证明了饮用水和废水的消毒、农药(除草剂)污染的水清洗和天然甲烷的转化(回收)效率。

We investigated the focusing properties of a double-ring-shaped azimuthally polarized beam tightly focused with a high NA lens and a binary phase filter. We observe that by using 3 belts and 5 belts binary phase filters novel focal patterns including splitting of focal rings and multiring focus are obtained. We also found that a suitably designed phase structure can shift the focal rings along optical axis. The author expects such investigation is worthwhile for optical manipulation and material processing technologies.

Pub Date : 2013-06-05 DOI: 10.1155/2013/791353

Plasma-assisted pretreatment (PAP) of lignocellulosic biomass has been shown to be an efficient method to decompose lignin and consequently facilitate microbial access to cellulose and hemicellulose. In the present study, PAP was tested for its suitability to enhance bioconversion of wheat straw to methane. In thermophilic batch experiments, methane yields of up to 366 mL/g volatile solids (VSs) were achieved, accounting for a yield increase of 45%. Common lignin-derived inhibitors like 5-hydroxymethylfurfural (5-HMF) and furfural were not detected after PAP, but toxicity test resulted in lower methane yields at higher substrate concentrations, indicating the presence of other unidentified inhibitors. However, in a continuous lab-scale biogas reactor experiment, stable codigestion of cattle manure with 20% PAP wheat straw was demonstrated, while no signs of adverse effects on the anaerobic digestion process were observed. After the introduction of the pretreated wheat straw to the reactor, volatile fatty acid concentrations remained low and stable, while gas production increased. In co-digestion, the PAP wheat straw was converted at an average yield of 343 mL CH4/gVS.
等离子体辅助预处理(PAP)木质纤维素生物质已被证明是一种有效的方法来分解木质素,从而促进微生物获得纤维素和半纤维素。在本研究中,试验了PAP对促进麦秸转化为甲烷的适宜性。在嗜热间歇实验中,甲烷产率达到366 mL/g挥发性固体(VSs),产率提高了45%。PAP未检测到常见的木质素衍生抑制剂,如5-羟甲基糠醛(5-HMF)和糠醛,但毒性试验结果表明,在较高的底物浓度下,甲烷产率较低,表明存在其他未知的抑制剂。然而,在连续的实验室规模的沼气反应器实验中,牛粪与20% PAP麦秸稳定共消化,而没有观察到对厌氧消化过程产生不利影响的迹象。将预处理过的麦秸引入反应器后,挥发性脂肪酸浓度保持较低且稳定,产气量增加。在共消化过程中,PAP麦秸的平均CH4产量为343 mL /gVS。
