Abstract [en]

The nonlocal and topological nature of the molecular Aharonov-Bohm (MAB) effect is examined for real electronic Hamiltonians. A notion of preferred gauge for MAB is suggested. The MAB effect in the linear + quadratic E circle times epsilon Jahn -Teller system is shown to be essentially analogues to an anisotropic Aharonov-Casher effect for an electrically neutral spin - 1/2 particle encircling a certain configuration of lines of charge.
