Research Interests Condensed Matter Physics, Experimental Low Temperature Physics, Quantum Liquids. He weak links. He quantum gyroscope. He phase slip sound. In research in condensed matter physics, phenomena of interest are often masked by competing effects involving impurities,defects, temperature inhomogeneities, and thermal fluctuations.
Liquid helium is the simplest condensed matter system.
It exists at temperatures down to absolute zero, is extremely pure, defect free, and devoid of spatial variations in temperature. It is an ideal system to test fundamental physical concepts. The most important aspect of the Helium liquids involves superfluidity. These discoveries have been honored by Nobel Prizes on 3 different occasions. The superfluid states themselves have been very important model systems to test and demonstrate physical theories.
