In the present paper, by applying Lang-Firsov canonical transformation and so-called noncrossing-approximation technique, we investigate effect of electron-phonon interaction on transport a quantum dot (QD) system in Kondo regime. The numerical results show that zero-frequency shot noise Fano factor are always enhanced significantly due to interaction. well-known peak structure around temperature S-V curve exhibits probe coupling strength λ. addition, enhancement is attributed reduction...
The use of lead-free ceramic film materials with positive temperature coefficient resistivity (PTCR) is widespread in heaters and sensors micro-electromechanical systems. In this research, the out plane transport properties BiFeO3 (BFO) films have been studied. Surprisingly, PTCR was found BFO due to strongly correlated interaction between multiferroic material superconductor YBCO perovskite oxides. To our knowledge, first report on effect films. BFO/YBCO interface bulk conductivity are...
We study the low-temperature differential conductance and density of states a quantum dot coupled to Luttinger liquid (LL) leads in Kondo regime using nonequilibrium Green's function approach. Around zero bias, peak decays finally vanishes with increasing intralead interaction, then dip develops for moderate interaction. The appearance manifests zero-bias anomaly (ZBA). It illustrates that combination Coulomb interaction on LL electrodes transition from one-channel physics two-channel...
In the present paper, by applying Lang–Firsov canonical transformation and so-called non-crossing approximation technique, we investigate joint effects of electron-phonon interaction an external alternating gate voltage on transport a quantum dot system in Kondo regime. We find that, while satellite resonant peaks appear both averaged local density states differential conductance, main peak at Fermi energy is greatly suppressed. These results confirm previous ones derived other methods, such...
In the present paper, we study effect of van Hove singularities conduction electron on transport a single quantum dot system in Kondo regime. By using both equation-of-motion and noncrossing approximation techniques, show that corrections caused by these are actually minor. It can be explained observing equations, which determine electronic DOS dot, integrable. Furthermore, find that, although each line width function is divergent at singular points, total divergence canceled out final...
This paper presents a design method for frequency selective surface (FSS) based on the deep neural network and improved particle swarm algorithm (IPSO). In proposed method, forward prediction (FPN) fully connected is established to fast predict transmission coefficient of FSS. Combined with FPN, IPSO used optimize structural parameters Compared traditional iterative optimization full-wave simulation, this greatly improves efficiency For example, band-stop FSS optimized in 210.6s, increases...
We establish a model to realize the photon-assisted destructive interference phenomena,the consisting of parallel-coupled double quantum dots and Luttinger liquid leads. By applying canonical transformation nonequilibrium Green’s function technique, general timedependent current formula is developed. The joint effects intralead Coulomb interaction an external ac field on are investigated. For weak interactions, besides usual tunneling resonance, there two types interference: one related...
