t-J model studied by the power Lanczos method
(American Physical Society, 1995-03)
The initial trial wave function used in a simple ground-state projection method, the power method, is systematically improved by using Lanczos algorithm. Much faster convergence to the ground state achieved by using these ...
First-principles study of several hypothetical silica framework structures
(American Physical Society, 1995-09-15)
Several hypothetical silica structures have been generated using a simulated-annealing strategy with an ab initio based covalent-bonding potential. First-principles total-energy pseudopotential methods have been used to ...
