简介: |
One of the great challenges in current studies on quantum
gases is that many important thermodynamic quantities have eluded from
experiments. In this talk, I will show how to reveal useful
information hidden in density profiles of trapped atoms. I will first
discuss a universal thermometry, which needs only the density profile
as input and is independent on any numerical simulation. I will then
focus on how to extract information of quantum criticality in quantum
gases from density profiles. A scheme to remove finite size effects
in a power-law trap will also be discussed. |
