What is the fate of the heavy electron at a quantum critical point?
A growing body of evidence suggests that the quantum critical behavior at the
onset of magnetism in heavy fermion systems can not be understood in terms of a
simple quantum spin density wave. This talk will discuss the consequences of
this conclusion, touching on its possible implications in the realm of two
dimensional systems and outlining current theoretical and experimental efforts
to characterize the nature of the critical point in heavy fermion materials.Comment: To appear in SCES 200
