How can the readers make improvements in reading? There are many skills to improve one’s ability of reading comprehension. I. The knowledge of words. One of the most important skills in reading is the knowledge of word. The number of the words you know determines the difficulty and complexity of the material you can read and understand. If you have an extremely limited reading vocabulary, you will be able to read only very simple material. Obviously, vocabulary forms a stumbling block for the poor reader. The more words you memorize, the faster you read the article. So, it is necessary to memorize words as much as you can.展开更多

It is found that the calculated results are in good agreement with those obtained by exact diagonalization (i.e., the exact values for a given basis set) when the population of psi particles (psips) is higher than the critical population required to correctly sample the ground state wave function. In addition, the variations of the average computational time per 20 Monte Carlo cycles with the coupling strength and the number of processors are also analyzed. The calculated results show that the computational efficiency of an FCIQMC calculation is mainly affected by the total population of psips and the communication between processors. These results can provide useful references for understanding the FCIQMC algorithm, studying the ground state properties of the 2D Hubbard model for the larger system size by the FCIQMC method and using a computational budget as effectively as possible.展开更多
