Bargmann invariants and off-diagonal geometric phases for multi-level quantum systems -- a unitary group approach

N. Mukunda, Arvind, S. Chaturvedi +1

We investigate the geometric phases and the Bargmann invariants associated with a multi-level quantum systems. In particular, we show that a full set of `gauge-invariant' objects f…
