to be understood. These correlations
appear quite different from those present
in the cuprates, which are mostly based
on Coulomb repulsion. On the other hand,
the metallic phase of the cuprates is also
known to harbor a “pseudogap”. Whether
there is any connection between these
two new states of matter is an interesting
challenge.
