Query: Pairing Correlations Near a Kondo-Destruction Quantum Critical Point   Motivated by the unconventional superconductivity observed in heavy-fermion
metals, we investigate pairing susceptibilities near a continuous quantum phase
transition of the Kondo-destruction type. We solve two-impurity Bose-Fermi
Anderson models with Ising and Heisenberg forms of the interimpurity exchange
interaction using continuous-time quantum Monte-Carlo and numerical
renormalization-group methods. Each model exhibits a Kondo-destruction quantum
critical point separating Kondo-screened and local-moment phases. For
antiferromagnetic interimpurity exchange interactions, singlet pairing is found
to be enhanced in the vicinity of the transition. Implications of this result
for heavy-fermion superconductivity are discussed.
