Contribution

It introduces a charge generation technique based on U(1,1) invariance and constructs a novel double rotating dyon solution with independent charges.

Findings

Developed a charge generation method using isometry subgroup

Constructed a new double rotating dyon solution

Demonstrated independence of physical charges in the solution

Abstract

The action of the isometry subgroup which preserves the trivial values of the fields is studied for the stationary D=4 Einstein--Maxwell--Dilaton--Axion theory. The technique for generation of charges and the corresponding procedure for construction of new solutions is formulated. A solution describing the double rotating dyon with independent values of all physical charges is presented.
