In the last several
years, a number of materials have been found whose properties do not seem to
fit in simply with conventional theories of the physics of solids. Striking
examples are the materials that display the remarkable phenomenon of high-temperature
superconductivity, but there are many others as well. Strong interactions between
the electrons in the solid and/or the presence of impurities play a crucial
role
in determining the properties of these materials. My research interests
are in understanding theoretically the phenomena that could and do arise in
such circumstances.
More specifically, my most recent interests have been in exploring the possibility
that the excitations in some such solids have quantum numbers that are fractions
of those of the electron. Put loosely, the electron has been broken apart! I
have also worked
on the theory of electron localization due to impurities in
various circumstances, and the properties of solids near zero temperature phase
transitions driven by quantum fluctuations.
