I summarize some of the key questions to have emerged during the 1994 conference on ``Strongly Correlated Electron Systems'', held in Amsterdam, August 1994. Issues addressed include: Hunds rule interactions and how they renormalize; the…
This year's SCES has proved exciting in the array of unconventional phenomena discovered both in novel systems, and by the renewed investigation of age-old systems, arguably in the vicinity of QCPs. From heavy fermion systems, to cuprate…

We study the dynamics of a quantum critical boson coupled to a Fermi surface in intermediate energy regimes where the Landau damping of the boson can be parametrically controlled, either via large Fermi velocity or by large N techniques. We…
