* ABSTRACT

Since the discovery of the BCS theory, the possibility of a pairing mechanism
in nature which is other than that of phonon exchange has attracted intensive
interest. While it is well established by now that various atomic systems
become paired states in certain situations, atoms are charge neutral and the
effective interactomic interaction responsible for pairing is simply
attractive. Therefore, remains the question whether there is a genuine pairing
mechanism caused by the repulsive interaction alone. In this talk, I would
like to focus on such a candidate in strongly correlated electron systems: the
fractional quantum Hall state in the half-filled second Landau level.
