outdir='./tmp'是输出电荷、波函数等文件所在目录,之后的nscf等计算要读入这些文件,所以要保持一致。prefix='pwscf'表示outdir目录下文件前缀,后续计算也要保持一致。 将输入文件保存成relax.inp,和两个赝势文件放在同一目录,运行pw.x < relax.inp > relax.out开始计算。(并行计算,安装了openmpi则
We determined the electronic structure of donor acceptor pairs in diamond and 3C-SiC using spin-polarized density functional theory (DFT), and the planewave pseudopotential method as implemented in the Quantum Espresso package61,62,63. The calculations of optical transition dipole moments were carried...
We perform electronic structure calculations with Quantum Espresso54, using norm-conserving pseudopotentials55 that include in the valence the 2s and 2p states of O, the 3s and 3p states of P, and the 3s, 3p, and 4s states of K. We find a stable classical ferroelectric structure of space...
can be calculated. As different results will be given by different functionals, it is necessary to specify what functional is used rather than simply referring to “a DFT calculation”. Herein, we will introduce four programs often used by researchers: Quantum Espresso, VASP, Materials Studio and...

The Espresso cipher, known for its ultra-lightweight design and energy efficiency, ensures minimal computational complexity, while the Grain stream cipher provides robust resistance against differential and linear cryptanalysis. The integration with QKD ensures unconditional security through qu...
The properties of AHfO3/BAgO3 perovskite materials (A = Cs, Ag; B = Cs, Ag) were comprehensively investigated using Density Functional Theory (DFT) to explore their structural, electronic, optical, mechanical, and X-ray core level spectroscopic attributes. The Quantum Espresso Simulation Package ...
