Query: Mass-Imbalanced Superconductivity in Effective Two-Channel Kondo Lattice   We propose that mass-imbalanced superconductivity is realized in an effective
two-channel Kondo lattice, and its characteristic property appears in
electromagnetic responses such as the Meissner effect. Starting from an
effective two-channel Kondo lattice model as a low-energy effective theory, and
approximating it with two mean-field order parameter components in a
self-consistent fashion, it is shown that the balance of the two components is
sensitively reflected in the magnitude of the Meissner kernel, while
thermodynamic properties are little affected by the balance. This remarkable
behavior is understood by the localized character of one partner in the Cooper
pair, namely, the effect of the mass imbalance. We briefly mention the
relevance to the huge enhancement of the upper critical field under pressure
observed in Pr 1-2-20 systems.
