A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
In this paper, with respect to the advantages of geometric phase in quantum computation, we calculate the geometric phase of the optomechanical systems. This research can be considered as an important step toward using the optomechanical systems in quantum computation with utilizing its geometric phase.
this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
In this study, the effect of fullerene electron mobility on the composition of paraphenylenediamine and stability was studied. Using quantum chemistry calculations, the first combination of paraffenylenediamine in a single-full-time region connected with fullerene through carbon atoms was reported. Experimental research was simulated and optimized using GIS software. Then the NBO calculations w...
The acid oxidation of carbon nanotube generally results in opening the close ends of the nanotube and to make surface modifications. Herewith, Multiwall carbon nanotubes (MWCNTs) were oxidized in acids at high temperature experimental conditions which led to the formation of graphene quantum dots (GQDs). High resolution transmission electron microscope (HRTEM), energy dispersive X-ray spectro...
the present work deals with the synthesis and characterization of cds nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. the nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. the prepared cds nanoparticles were compared with the bulk cds. the optical properties were determin...
In order to study the effect of irrigation levels and plant growth promoting rhizobacteria on yield, some physiological and biochemical indices of rapeseed, a factorial experiment was conducted based on randomized complete block design with three replications in Agricultural Research Station of Ardabil, Ardabil, Iran in 2016. The factors included in the experiment were irrigation in three level...
The purpose of this study was to present a competence model for leaders of quantum organizations. This research was exploratory and mix method (qualitative and quantitative). In the qualitative part of the statistical society, the research was conducted by professors of management from different universities and the statistical population of the quantitative part of the research consisted of th...
Fingerprint identification or dactyloscopy is a method for human identification. The impressions left by a human finger on surfaces are not visible to naked eyes (latent fingerprint); therefore, they require revelation to become visible and identified. Within the last century, several fingerprint revelation techniques such as optical, physical, and chemical were studied. These traditional metho...
Nowadays study of chaotic quantum billiards because of their relation to Nano technology. In this paper distribution of zeros of wave function on the boundary of two circular and stadium billiards are investigated. By calculating gyration radius for these points chaotic and non-chaotic states are distinguished.
