The electronic transport in an infinite arrays of driven quantum wells coupled to a quantum ring is studied via a single-band tunneling tight-biding Hamiltonian by perturbing and numerical simulations approaches. In the perturbing approach, an analytical relationship in terms of the coupling constants between nearest-neighbors in quantum wire coupled to a ring based on the quantum dynamical alg...
Because the key issue in quantum information and quantum computing is entanglement, the investigation of the effects of environment, as a source of quantum dissipation, and interaction between environment and system on entanglement and quantum phase transition is important. In this paper, we consider two-qubit system in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-moriya inter...
The propagation of nonlinear quantum dust ion-acoustic (QDIA) solitary waves in a unmagnetized quantum plasma whose constituents are inertialess quantum electrons and positrons, classical cold ions and stationary negative dust grains are studied by deriving the Korteweg–de Vries (KdV) equation under the reductive perturbation method. Quantum Hydrodynamic (QHD) equations are used to take into ...
Using the quantum game formalism in 3-player system, we calculate the Nash equilibrium in quantum Prisoners’ Dilemma by increasing parameters of unitary operator. Since, the entanglement plays an important role in quantum states of particles quantum game, actually its effect on the obtained results of Nash equilibrium is investigated. It is shown that increasing the parameters enhances the gam...
the electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting hamiltonian anderson tunneling method. in this paper we concentrate on the configuration of the quantum dot rings. we show that the asymmetric structure of qd-scatter system strongly influences the amplitude an...
the comparison of growth processes and fluorescent properties of cdznte semiconductor quantum dots that are synthesized in different concentrations of zn2+ in water are discussed in this paper. the samples are characterized through absorbtion (uv) and photoluminescence spectra (pl). the results show that when the reaction time is prolonged, the absorption peak and fluorescent emission peak pres...
in this work, we report, optical properties of cd1-xsnxte quantum dots (x= 0.05, 0.10 and 0.15) synthesized in water using thioglycolic acid (tga) as a modifier agent. the optical characterization of the samples was performed through absorption (uv) and photoluminescence spectra (pl). a red shift absorption and fluorescent emission peaks was observed which can be related to the increase of nano...
OBJECTIVE Recent studies have recognised that the communication skills learned in the training environment are not always transferred back into the clinical setting. This paper reports a study which investigated the potential of clinical supervision in enhancing the transfer process. METHODS A randomised controlled trial was conducted involving 61 clinical nurse specialists. All attended a 3-...
OBJECTIVE This study explored and compared medical students' attitudes toward communication skills and empathic tendency before and after communication skills training. METHODS Fifty-nine first-year students voluntarily completed a questionnaire consisting of the Communication Skills Attitudes Scale and the Empathic Tendency Scale before and after training. K-means cluster analysis and Studen...
