Abstract: The topological properties of adiabatic gauge fields for multi-level (three-level in particular) quantum systems are studied in detail. Similar to the result that the adiabatic gauge field for SU(2) systems (e.g. two-level quantum system or angular momentum systems, etc) has a monopole structure, the curvature 2-forms of the adiabatic holonomies for SU(3) three-level and SU(3) eightlevel quantum systems are shown to have monopole-like (for all levels) or instanton-like (for the degenerate levels) structures. © 2007 IOP Publishing Ltd.
