Our focus is on
experimental low-temperature physics.
We have studied the universal scaling of the two-dimensional
superfluid phase transition of 4He films and the effects of
impurities on the growth dynamics of the 4He solid-liquid
interface using crystallization waves. One of our current projects is investigating the potential of
a new configuration for inelastic electron tunneling spectroscopy (IETS)
and the development of a low temperature scanning probe microscope capable
of performing IETS.
