    "abstract": "The role of Aharonov-Bohm effect in quantum tunneling is examined when a\npotential is defined on the $S^1$ and has $N$-fold symmetry. We show that the\nlow-lying energy levels split from the $N$-fold degenerate ground state\noscillate as a function of the Aharonov-Bohm phase, from which general\ndegeneracy conditions depending on the magnetic flux is obtained. We apply\nthese results to the spin tunneling in a spin system with $N$-fold rotational\nsymmetry around a hard axis.",
