This section includes descriptions for algorithms used in the two essential software packages developed in this study. Section 4.1 describes the algorithms for simulating the SPDC and interaction with the object. Section 4.2 describes the data…

Realization of polarization-independent function

To achieve polarization-independent functionality, the device described in this study utilizes a slot waveguide structure, which results in an electric field discontinuity between materials with…

The C-band of microwave frequencies, spanning from 4 to 8 GHz, is a sweet spot for circuit QED and quantum computing applications. From a practical perspective, RF electronics is commonly optimized to work in this frequency range. From a…

Pure-state model for resonance fluorescence and its predictions

Figure 1a depicts the spontaneous emission model. A monochromatic laser coherently drives a TLE, e.g., a QD in a micropillar cavity¹¹. Parameters ν, hν and T_L are the laser’s…

Simulation of dynamic electron avalanche process

Taking BaTiO₃ as an example, we first analyze the possible region where collision ionization and bond breakage occur by comparing the atomic features in a unit cell. As shown in Fig. 2a, owing to…

Fabrication of TSD- and TED-dominant GaN Epitaxy

To introduce distinct dislocation configurations, two GaN epitaxial structures were grown on sapphire substrates via metal-organic chemical vapor deposition (MOCVD). For TSD-dominant samples, a…

Initial equations

Now, we investigate a DT type atomic system (Fig. 1b) involving three metastable ground states \(|0\rangle\), \(|1\rangle\) and \(|2\rangle\), as well as excited states \(|e_{1}\rangle\) and \(|e_{2}\rangle\). Six laser fields…

The half-Heusler XYZ compound exhibits a non-centrosymmetric cubic structure, crystallizing in the cubic C1_b crystal structure with the F\(\:\stackrel{-}{4}\)3m space group, where X and Y are transition metal or rare earth elements, while Z is a…

UAV imagery and crack characteristics

Based on their morphology and propagation trends, cracks in bridge pavements can be classified into four types: transverse, longitudinal, block, and grid cracks. The two types share several common…

Preparation and structures of M-HHTP and M-TCPP

A series of EC-MOFs and IC-MOFs films were fabricated through a facile LBL-LPE method at room temperature, achieving controllable film orientation/thickness and adjustable metal ion (Ni, Cu, Zn) and…
