Hidden geometric phases and holonomies of four level system
We derive a set of new geometric phases (holonomies) in a four-level system exploiting accidental isomorphism between SU(4) and Spin(6) groups. Higher dimensional generalization of the Bloch sphere, visualizing quantum geometry of 4-level system, is described. © 2005 Optical Society of America.
