  Current enhancement- a novel quantum phenomena is found to occur in a
mesoscopic hybrid ring at equilibrium. The hybrid system is described by a ring
with bubble which is in turn coupled to a reservoir. In the system the ring
encloses a magnetic flux $\Phi$ while the bubble does not enclose any flux. The
novelty of this work lies in the fact that while earlier current enhancement
was observed in non-equilibrium systems (e.g., a ring coupled to two reservoirs
at different chemical potentials $\mu_{1}$ and $\mu_{2}$), herein we prove that
current enhancement can also arise in equilibrium. In addition, we show that
the closed system analog of our chosen open hybrid ring system violates parity
effects. Finally, we bring to focus the discrepancy between the equilibrium
magnetic moment (obtained via energy eigenvalues) and that calculated from the
currents in the system.
