Pappalardo Fellow in Physics: 2010-2013
Name: Karen Michaeli
Title(s):Pappalardo Fellow in Physics: 2010-2013
Massachusetts Institute of Technology
Area of Physics:
Hard Condensed Matter Theory
Karen Michaeli's research interests lie in the field of interacting electron systems, with a focus on quantum transport phenomena in interacting systems; localization-delocalization effects and quantum dissipation; thermoelectric phenomena close to quantum critical points; vortex dynamics; new electronic phases at oxide interface structures; unconventional superconductivity and spin-orbit coupling. She also plans to study phase transitions in correlated electron systems such as the many-body localization and the superconductor-insulator transitions.
Karen Michaeli completed her Ph.D. from the Weizmann Institute of Science in the summer of 2010. While there, she worked with Prof. Alexander Finkel’stein on thermal and thermoelectric transport phenomena in the presence of electron-electron interaction and disorder. As a part of her Ph.D. thesis, Michaeli developed a new theoretical apparatus for analyzing thermal and thermoelectric transport using the quantum kinetic equation. She used this approach to show that the strong Nernst effect observed recently in amorphous superconducting films above the critical temperature (as well as for magnetic fields considerably exceeding Hc2) is caused by the fluctuations of the superconducting order parameter.
Michaeli earned her M.Sc. from the Weizmann Institute of Science in 2006 on the study of the suppression of the tunneling rate of superconducting vortices caused by magnetic coupling to a remote metallic gate.
