SENTHIL TODADRI, Associate
Professor of Physics
Research Interests
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.
Professor Todadri's research interests are in understanding, theoretically,
the phenomena that could and do arise in such circumstances.
More specifically, his 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! Professor
Todadri has 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.

Biographical Sketch
Senthil Todadri joined MIT in January 2001
as an Assistant Professor of Physics, and received tenure in early 2007. Before that, he had spent
a few years as a postdoctoral fellow at the Institute for Theoretical
Physics in Santa Barbara, CA. His graduate degree is from Yale University,
and undergraduate from the Indian Institute of Technology, Kanpur.
