Instanton-meron hybrid in the background of gravitational instantons
Journal Article

· Physical Review D
In the present work, perhaps the simplest and the most straightforward new algorithm for generating solutions to the (anti-)self-dual Yang-Mills (YM) equation in the typical gravitational instanton background is proposed and then applied to find solutions to practically all the known gravitational instantons. The solutions thus obtained turn out to be some kind of instanton-meron hybrids possessing mixed features of both. Namely, they are rather exotic type configurations obeying a first order (anti-)self-dual YM equation which are everywhere nonsingular and have finite Euclidean YM actions on one hand while exhibiting meronlike large distance behavior and carrying generally fractional topological charge values on the other. Close inspection, however, reveals that the solutions are more like instantons than merons in their generic nature.
