As long as you only do one transform, then perform linear manipulations in the frequency domain, then do an inverse transform, it does not really matter, which way you scale the transforms, however, when we calculate the convolution of two vectors by taking the DFT/FFT of both...

(离散)傅立叶变换DFT几乎存在我们生活周遭,手机拍照图像处理辨识,声音处理,与5G通讯都少不了他,他是个数据处理的过程,把原本量测到的时域讯号转换到另外一个频域讯号,如果有N个取样数据,转换到另外一个平面也会得到N点数据。而且可以进行逆转换Inverse DFT, 如果原本数据是频率讯号也可以透过inverse DFT得到时域讯号...
CONQUEST是一种专为大规模计算而设计的DFT代码,具有出色的并行性。它为1到10,000+原子的系统提供了一致和精确的对角化方法,并提供了对超过1,000,000个原子进行线性缩放计算的可能性。该代码已被证明可以扩展到将近200,000个核和2,000,000个原子。 CONQUEST可以执行静态电子结构计算(包括DOS和能带结构计算)、结构弛...
Density functional theory (DFT) calculations have been playing important roles to clarify the structures of semiconductor surfaces at atomic scale. However, DFT studies of complex nanostructures are usually impossible because conventional DFT methods cannot treat large systems containing many thousands of at...
CONQUEST: Large-scale DFT calculations CONQUEST is a DFT code designed for large-scale calculations, with excellent parallelisation. It gives a consistent, exact diagonalisation approach for systems from 1 to 10,000+ atoms, and brings the possibility of linear scaling calculations on over 1,000,...
Using large-scale DFT calculations, we have investigated the structural and electronic properties of both armchair and zigzag graphdiyne nanotubes as a function of size. To provide insight in these properties, we present new detailed calculations of the structural relaxation energy, effective electron/ho...
