This question has attracted much attention recently. Ref. [1] has pointed out that black holes can carry nonclassical discrete charges; Ref. [2] has studied the black holes with axion charges; Ref. [3] has discussed the existence of Skyrm charges on black holes; and Ref. [4] has investigated the problem whether black holes can carry QCD color charges.展开更多
