Cave Lecture


Can a solid be superfluid?

M. H. W. Chan
Penn State University

Time
 
Mon. March 28, 2005     2:30 PM     Stirling A

Abstract
 
Our recent experiments found evidence that answer the question, amazingly, in the affirmative. I will report on the observation of non-classical rotational inertia in solid He-4 confined to an annular channel in a sample cell under torsional motion, demonstrating sueprfluid behavior. Measurement of solid samples at different pressure (and hence different density) allows us to map out the phase boundary of this supersolid. These results indicate that superfluid behavior is found in all three phases of matter; gas, liquid and solid. This work is carried out in collaboration with Eunseong Kim and it is supported by the National Science Foundation of US.

Professor M.H.W. Chan is the Cave Lecturer for 2005. Professor Chan is Evan Pugh Professor of Physics at the Pennsylvania State University, member of the National Academy of Sciences in the United States and winner of the Fritz London Prize in Low-Temperature Physics.

All are welcome to this lecture, and refreshments will be available after the talk. This is the more technical of two lectures being given by Professor Chan, the second one will be a public lecture held in Stirling D at 8pm.
