    ABSTRACT: We have studied a spatially flat Friedmann–Lemaître–Robertson–Walker (FLRW) cosmological model with an additional assumption that the universe is filled with barotropic causal bulk viscous fluid. The bulk viscous coefficient of the fluid is related to the energy density and relaxation time by the relation . We have used a truncated version of the transport equation for the viscous pressure. The expansion rate of such a spatially flat FLRW universe is governed by the well-known modified Painlevé–Ince equation. We find that the Lie symmetry corresponding to scale invariance gives the power-law solution for this model equation from invariant curve condition. For the value of , our result satisfies the present experimental value of the deceleration parameter (q) for . The result obtained for the relaxation time which is of the order of the Hubble time supports the necessary condition for successful inflation. Our study not only shows the role of the bulk viscosity for the present accelerating expansion but also predicts an age of around , which solves the age problem of the present universe.

    ABSTRACT: The technique regarding the integration within a normally ordered product of operators, which refers to the creation and annihilation operators of the harmonic oscillator coherent states, has proved to be very fruitful for different operator identities and applications in quantum optics. In this paper we propose a generalization of this technique by introducing a new operatorial approach—the diagonal ordering operation technique (DOOT)—regarding the calculations connected with the normally ordered product of generalized creation and annihilation operators that generate the generalized hypergeometric coherent states. We have pointed out a number of properties of these coherent states, including the case of mixed (thermal) states. At the same time, by particularizing the obtained results to the one-dimensional harmonic and pseudoharmonic oscillators, we get the well-known results achieved through other methods in the corresponding coherent states representation.

    ABSTRACT: In 1912, Laue spots were discovered in x-ray scattering 'photograms' of crystals, which were amongst the most consequential experimental findings of the 20th century. Inter alia, spots established the x-ray waves and crystal lattice; plus, for the first time ever, revealed atoms as real physical objects. Laue, a protégé of Planck and a wave-optics expert, had theoretically predicted these spots, and promptly won the Physics Nobel Prize for 1914. The prize did not come easy: executing his experimentum cruces, over the judgments of Sommerfeld and Wien, required force of will and a certain amount of diplomacy. Besides, his explanation for missing spots and x-ray diffraction were proven wrong by Moseley, Darwin and the two Braggs. Traditionally, Laue's three-dimensional diffraction model is reconciled with Bragg's reflection formula by Ewald's construction using reciprocal lattice space. Laue had overlooked that his fundamental equations violate Euclidean length invariance. This article shows that implementation of invariance consolidates Laue's system of three (multi-parameter) equations into a single formula containing one integer, one angle and two distances; plus validating Bragg's conjecture of reflection. This new derivation demonstrates that the mechanism of Laue spots is akin to the anti reflection coating the colour-plays in soap bubbles and oil slicks—reflection and interference not diffraction. Yet, Laue stimulated countless breakthroughs: Nobel Prizes and scientific innovations, with an enduring legacy of inspiration a century later.

    ABSTRACT: The ideal magnetohydrodynamic (MHD) ballooning instability is investigated using an up-down symmetric local equilibrium model [W Yu et al 2012 Phys. Plasmas 19 072520] in a tokamak plasma with a shaped cross section. The influence of the shaping factors on the transition to the second stability region is stressed. Since the local equilibrium solution is expressed using eight independent parameters, and the derivative of the Shafranov shift is self-consistently determined in the model, the effect of the single shaping factor can be studied separately without equilibrium construction repeatedly. We found that the increasing elongation provides some improvement for the transition to the second stability region when holding other parameters fixed. In addition, positive plasma triangularity is more favorable for access to the second stable region than negative triangularity for moderate elongation.

    ABSTRACT: An information theoretic approach developed by Schack and Caves known as hypersensitivity to perturbation is applied to some operators relevant to quantum computation, namely the Hadamard transform, the Fourier transformed columns of the Hadamard transform and the Modulo exponentiation operator. While the Hadamard transform shows intermediate sensitivity to perturbation, the Fourier transformed columns of the Hadamard transform and the Modulo exponentiation operator, a crucial ingredient of Shor's factoring algorithm shows sensitivity to perturbation, unlike Grover's search algorithm, which is not known to be hypersensitive to perturbation.

    ABSTRACT: In this paper, we exploit the notions of tripartite quantum discord , tripartite negativity , and entanglement witnesses (EWs), respectively, as a measure of quantum correlations in a model of three noninteracting qubits subject to a classical random external field. We compare the dynamics of with that of entanglement for the initial entangled pure or mixed GHZ- and W-type states. We find that the quantum correlations dynamics depend on the input configuration of the purity of the initial states. The results show that may be more robust than entanglement and no sudden death of the occurs, whereas entanglement displays periodically sudden death and revivals in the regions for GHZ- and W-type states driven by a classical random external field. Furthermore, we also show that the survival partial entanglement can be detected by means of the suitable EWs.

    ABSTRACT: We introduce the definition of strong structural control centrality, which represents the dimension of strong structurally controllable subspace or the capability of a single node to control an entire directed and weighted network in a strongly structural manner. A purely algebraic algorithm to calculate strong structural control centrality is proposed. Then we explore the quality of the strong structural control centrality. The relation between strong structural control centrality and the layer index in a directed tree inspires us to research (1) some fast methods to achieve strong structural control centrality and (2) the size relationship of strong structural control centralities of nodes belonging to different supernodes.

    ABSTRACT: The electrorheological (ER) effect is known as the change in the apparent viscosity upon the application of an external electric field perpendicular to the flow direction. In this work we present the electrorheological behaviour of suspensions in silicone oil of two different dispersed phases: foams of liquid crystal 4-n-penthyl-4'-cyanobiphenyl (5CB) encapsulated in polyvinyl alcohol (PVA) and nano/microspheres of 5CB encapsulated in silica. We will present the viscosity curves under the application of an electric field ranging between 0 and 3 kV mm−1. The ER effect was observed for the suspensions of 5CB/PVA but not in the case of 5CB/silica. For the case of the suspensions of 5CB/PVA, the effect of the viscosity of the continuum phase and the concentration of the dispersed phase was analysed, showing that the enhancement of the viscosity of the suspension increases with the concentration, as expected, however the continuum phase viscosity has no significant effect, at least in the investigated viscosity range.

    ABSTRACT: The effects of laser fluence on the surface morphology of zirconium films grown onto Si (100) by pulsed laser deposition are investigated. We found that the average nanoparticle size and the root mean square (RMS) roughness of Zr films increase with increasing laser fluence. The presence of droplets on the surface of deposited films, which is one major shortcoming of pulsed laser deposition (PLD), was studied at different laser fluences, pulse repetition rates, and substrate temperatures. In this paper, the distribution of droplets was well investigated in detail. In order to have more control of the deposition process, we investigate the influence of deposition time, laser fluence, and pulse repetition rate on the deposition rate. The research work in this paper lays the foundation for further obtaining the fine characteristics of Zr thin films.

    ABSTRACT: The validity of the traditional plasma continuum is predicated on a hierarchy of scale-lengths, with the Debye length being considered to be effectively unresolvable in the continuum limit. In this article, we revisit the strong magnetic field case in which the Larmor radius is comparable or smaller than the Debye length in the classical plasma, and also for a relativistic plasma. Fresh insight into the validity of the continuum assumption in each case is offered, including a fluid limit on the Alfvén speed that may impose restrictions on the validity of magnetohydrodynamics (MHD) in some solar and fusion contexts. Additional implications concerning the role of the firehose instability are also explored.
