Shifted COCG method and its application to double orbital extended Hubbard model
Susumu Yamamoto, Tomohiro Sogabe, Takeo Hoshi +2
We explains the shifted COCG method which can solve a series of the linear equations generated by numbers of scaler shifts, without time consuming matrix-vector operations, except…

Linear Algebraic Calculation of Green's function for Large-Scale Electronic Structure Theory
R. Takayama, T. Hoshi, T. Sogabe +2
A linear algebraic method named the shifted conjugate-orthogonal-conjugate-gradient method is introduced for large-scale electronic structure calculation. The method gives an itera…
