Current Research

The main interest of our group is directed toward an understanding of the macroscopic quantum properties of superfluid 3He, 4He, and the super solid state of solid 4He. The problems of Bose-Einstein condensation, inhomogeneous superfluid boundary conditions and the study of phase transitions in systems of reduced dimensionality are current research topics of my group. Persistent current studies, torsional oscillator measurements, nano kelvin thermometry, and propagation of 3rd and 4th sound are examples of the various experimental techniques used in this work. The group has a close association with those of Professors Lee and Parpia.

Our group will consider a new graduate student.

Spotlight

Jalina Keeling is an undergraduate student with the Itai Cohen Group on Complex Matter Physics (who is at Cornell as part of the NSF's Research Experiences for Undergraduates program). She is conducting experiments similar to the epitaxial growth of crystals, but using polymer beads. She uses a confocal microscope to scan a sample of these beads from bottom to top. Her research seeks to answer the questions "What structures form? How do we tune the concentration of polymers to change ...
