The Weibel instability in the quantum plasma case is treated by means of a fluid-like (moments) approach. Quantum modifications to the macroscopic equations are then identified as effects of first or second kind. Quantum effects of the first kind correspond to a dispersive term, similar to the Bohm potential in the quantum hydrodynamic equations for plasmas. Effects of the second kind are due t...
We review recent progress in open quantum system approach to the description of quarkonium quark-gluon plasma. A particular emphasis is put on Lindblad equations for and its numerical simulations.
quantum theory poses itself to be a challenging counterpart to the intelligent design argument. quantum physics founded upon uncertainty, probability and statistics has exerted great influence since its inception on the philosophical thinking of man. the findings of this theory has helped bring about a dramatic transformation in the notion of ‘order in nature.’ in modern physics, it is hardly p...
This study seeks to design a new and innovative model for school management using the data foundation method, a model that can be an effective aid in solving the problems and challenges facing school principals by using quantum leadership. Designing a quantum leadership model in secondary schools based on data theory is the main goal of this research and seeks to achieve a suitable model for ov...
The optical conductivity sigma (omega) for dense Coulomb systems is investigated using molecular dynamics simulations on the basis of pseudopotentials to mimic quantum effects. Starting from linear response theory, the response in the long-wavelength limit k=0 can be expressed by different types of autocorrelation functions (ACF's) such as the current ACF, the force ACF, or the charge density A...
Background: Quantum dots are commonly composed of cadmium contained semiconductors. Cadmium is potentially hazardous but toxicity of such quantum dots is not yet systematically investigated. On the other hand, in vitro studies have shown almost complete control of CdSe induced cytotoxicity by ZnS coverage. Toxicity of CdSe quantum dots and controlling this toxicity by ZnS coverage in immature m...
thrombotic thrombocytopenic purpura is the result of multiple thrombus disseminated in small arterioles throughout the body. principle damage is in the endothelium of small vessels and capillaries. from 1982 to 1999, 28 patients (16 female and 12 male) have been treated for ttp. the outcome was evaluated for risk factors and prognosis. these patients were 18 to 69 years old. all had neurologica...
Analytical and numerical studies are presented for electron acoustic solitary wave structure in relativistic degenerate two-component unmagnetized astrophysical plasma. The existence of a wave mode of pure quantum origin is predicted. The effect of various plasma parameters on the conditions of existence and properties of solitary wave is investigated. It is shown that depending on the values o...
Interactions between particles in quantum many-body systems can lead to collective behavior described by hydrodynamics. One such system is the electron-hole plasma in graphene near the charge-neutrality point, which can form a strongly coupled Dirac fluid. This charge-neutral plasma of quasi-relativistic fermions is expected to exhibit a substantial enhancement of the thermal conductivity, than...
We demonstrate that a Bjorken expanding strongly coupled $\mathcal{N}=4$ Supersymmetric Yang-Mills plasma can display dynamically-driven violations of the dominant and also weak energy condition during hydrodynamization. In addition, we find period vanishing entropy production in far-from-equilibrium stages induces later plasma. Such cannot occur classical description hydrodynamization suggest ...
