  3. 2. Comparison of accelerated recursive polynomial expansions for electronic structure calculations

    University essay from

    Author : Carl Joneus; Oskar Wretstam; Filip Enander; [2015]
    Keywords : Electronic structure calculations; Density matrix; Polynomial expansion; Purification;

    Abstract : In electronic structure calculations the computational cost is of great importance because large systems can contain a huge number of electrons. One effective method to make such calculations is by density matrix purification. Although, the cost for this method is relatively low compared to other existing methods there is room for improvements. READ MORE
