PATRICK A. LEE, William
& Emma Rogers Professor of Physics;
Division Head, Atomic, Biological, Condensed Matter and Plasma Physics
Research Interests
Professor Lee's main research interests lie in the study of strongly
correlated electronic systems. These are materials where the interactions
between electrons play a crucial role and lead to novel phenomena
not explainable by single electron band structure effects. Examples
include the quantum Hall effect, mesoscopic systems, and effects
due to disorder.
More recently, Professor Lee's research is focused on the problem
of high temperature superconductivity. The starting point of this
work is that the new family of superconductors is an example of
the doped Mott insulator. The parent material is an antiferromagnetic
insulator that is insulating due to correlation effects. Doping
introduces carriers into the insulator, leading to a rich variety
of novel phenomena including superconductivity. Methods of attack
include many-body field theory and numerical work.

Biographical Sketch
Professor Lee joined the MIT Department of Physics in 1982 after
approximately ten years with the Theoretical Physics Department
at Bell Laboratories. He has made key contributions to the theory
of disordered electronic systems and is a pioneer in "mesoscopic
physics," the study of small devices at low temperatures. Professor
Lee introduced the concept of universal conductance fluctuations
to describe such devices. For this, and other contributions to condensed
matter physics, he was awarded the 2005 Dirac Medal of the International Centre for Theoretical Physics and the Oliver Buckley Prize of the American
Physical Society. Professor Lee's current research interests focus
on high temperature superconductors.
