The time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. Quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. It is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. The phase dependence of the atom-field entanglement is...

The paper deal with non-commutative geometry. The notion of quantumspheres was introduced by podles. Here we define the quantum hermitianmetric on the quantum spaces and find it for the quantum spheres.

A molecular imprinted polymer (MIP) was computationally designed and synthesized for the selective extraction of metaproterenol (MTP), from human plasma. In this regards semi empirical MP3 and mechanical quantum (DFT) calculations were used to find a suitable functional monomers. On the basis of computational and experimental results, acrylic acid (AA) and DMSO:MeOH (90:10 %V/V) were found to b...

The authors study the dynamics of droplets quark-gluon plasma created in heavy iron collisions. relativistic quantum fluid undergoes Bjorken flow expansion and is modeled as conformal $N=4$ supersymmetric Yang-Mills plasma. In particular, they investigate holographic entropy production far from equilibrium where horizon area no longer a proper measure for but dynamic apparent assumed to be righ...

Modular peptides displaying both quantum dot bioconjugation motifs and specific subcellular targeting domains were constructed using a chemoselective aniline-catalyzed hydrazone coupling chemistry. Peptides were ratiometrically assembled onto quantum dots to facilitate their specific delivery to either the plasma membrane, endosomes, the cytosol or the mitochondria of target cells.

Ion-acoustic solitary and shock waves in dense quantum plasmas whose constituents are electrons, positrons, and positive ions are investigated. We assume that ion velocity is weakly relativistic and also the effects of kinematic viscosity among the plasma constituents is considered. By using the reductive perturbation method, the Korteweg–deVries–Burger (KdV-B) equation is derived. Keywords—Ion...

The Jeans instability of infinite homogeneous, self-gravitating quantum plasma is investigated under the assumption of optically thick medium and black body radiation. The general dispersion relation is obtained and the condition of instability is discussed.

A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...

Recently, codes over some special finite rings especially chain rings have been studied. More recently, codes over finite non-chain rings have been also considered. Study on codes over such rings or rings in general is motivated by the existence of some special maps called Gray maps whose images give codes over fields. Quantum error-correcting (QEC) codes play a crucial role in protecting quantum ...

To achieve a high-density electron-hole plasma in group-III nitrides for efficient light emission, we propose a planar two-dimensional (2D) p − i − n structure that can be created in selectively-doped superlattices and quantum wells. The 2D p − i − n structure is formed in the quantum well layers due to efficient activation of donors and acceptors in the laterally doped barriers. We show that s...
