overview
............................................................................................................................................................................
Professor Yu earned her A.
B. (1979)
and Ph.D. (1984) from Princeton University. She did postdoctoral
research at the University of Illinois at Urbana-Champaign and Los
Alamos National Laboratory before joining the faculty at UCI in 1989.
She is the recipient of a Sloan Research Fellowship.

summary
............................................................................................................................................................................
In
the last decade the discovery of
high-temperature superconductors and heavy fermion superconductors has
led to a great deal of interest in the phenomena that result when
electrons strongly interact with one another. Examples of such
phenomena are superconductivity, various sorts of magnetism, and
electrons which acquire effective masses hundreds of times larger than
bare electron masses. Seemingly simple models of these systems, such as
the Kondo and the Anderson lattice models, show a rich variety of
behavior. Professor Yu has been studying these models using numerical
renormalization group techniques.
Another
focus of Professor Yu's
research has been the study of disordered systems such as glasses and
spin glasses. A bunch of molecules in a disordered jumble behaves very
differently from an ordered crystalline array of those same molecules.
This can be seen in the lowtemperature thermodynamic properties such as
the specific heat and thermal conductivity. These properties of glassy
systems tend to be universal, independent of the particular material
and its chemistry. What is it about the nature of disorder that gives
rise to such universal properties? This is the basic problem of
disordered systems. For the past twenty years, it has been thought that
independent tunneling centers are responsible for the low-temperature
properties of glasses.
However,
it has been increasingly
apparent that interactions among defects must be incorporated into our
understanding of glasses. Professor Yu has been pursuing this approach
by performing Monte Carlo simulations of an interacting defect model of
glasses. She and members of her research group have also been working
with experimentalists to try to understand the physics of disordered
systems.
Professor Yu has taught graduate
courses in Condensed Matter Physics as well as undergraduate courses on
Electricity and Magnetism.
