Query: The Geometric Phase in Supersymmetric Quantum Mechanics   We explore the geometric phase in N=(2,2) supersymmetric quantum mechanics.
The Witten index ensures the existence of degenerate ground states, resulting
in a non-Abelian Berry connection. We exhibit a non-renormalization theorem
which prohibits the connection from receiving perturbative corrections.
However, we show that it does receive corrections from BPS instantons. We
compute the one-instanton contribution to the Berry connection for the massive
CP^1 sigma-model as the potential is varied. This system has two ground states
and the associated Berry connection is the smooth SU(2) 't Hooft-Polyakov
monopole.
