What happens to an electron-system when interactions dominate? What is the role of disorder in such systems? Is the 1/R^2 law of gravitational force true at all length scales?
Professor Kapitulnik studies materials with novel electronic states at low temperatures. The research concentrates on the occurrence and properties of superconductivity, charge-density, or magnetic states in such systems. The group uses a variety of measurements and novel probes such as scanning tunneling microscopy and spectroscopy and high-resolution mageneto-optics.
A variety of recent theories of physics beyond the Standard Model would, if true, lead to deviations from Newtonian gravity on experimentally accessible length scales. To detect or constrain such deviations, we constructed two experiments, both with cantilever-based probes, to directly measure the force between two masses separated by tens of microns. Our apparati include novel solutions to experimental challenges culminating in detection capability of forces at the range of attonewton (10^-18N) strength.
Current areas of focus:
- Physics of disordered systems
- Thin films and physics of low-dimensional systems
- Vortex physics
