| Abstract: | In this paper we have proposed a new quantum ground state approximation theory in virtue of the determinant representation. By using the linear virational principle,we have deduced the very simple form for finding the eigenvalue and eigenfunction of the quantum ground state. It has simplified and generized the conclusion of SDATCthe Steepest Descent Approximation Theory),and will applicate to physical calculation in many fields. |
