Abstract
In recent years some numerical methods have been developed to integrate matrix differential systems whose solutions are unitary matrices. In this paper we study numerical methods for the special class of unitary systems the solutions of which are Hermitian matrices throughout the evolution. Several numerical comparisons with known unitary integrators are reported.File in questo prodotto:
