    "abstract": "We consider adiabatic transport of eigenstates of real Hamiltonians around\nloops in parameter space. It is demonstrated that loops that map to nontrivial\nloops in the space of eigenbases must encircle degeneracies. Examples from\nJahn-Teller theory are presented to illustrate the test. We show furthermore\nthat the proposed test is optimal.",
