Hans Bozler

The Ultralow Temperature Physics group led by Hans Bozler and Chris Gould is one of only a few laboratories in the world capable of examining the properties of matter at temperatures less than one one-thousandth of a degree above absolute zero. While both faculty maintain separate research programs, there is a great deal of overlap and cooperation between them. The most significant research area for the group has been a long-term program of study of the superfluid phases of liquid 3He (including precision thermodynamic, dynamic magnetic, and hydrodynamic studies). In addition to this the ULT group is studying the strong magnetism induced in normally weakly magnetic 3He when placed next to walls, and issues regarding electron transport in metallic systems at ultralow temperatures. The group has a long history of developing ultralow temperature measurement techniques, and is presently developing instruments based upon single electron transistors and superconducting quantum interference devices.
