Low Temperature Physics

In this project, ultrasonic measurements have been used in order to observe the influence of uniaxial stress on the elastic properties of the ferroelastic compound Rb4LiH3 (SO4) 4. The experimental results are compared to predictions derived from a Landau model. In the experimen…

A Bose-Einstein condensate of atomic vapor has proven in the past decade to be a simple enough system to follow theoretic predictions with great accuracy. Still, the control over all parameters gives a rich system, abundant with new physical phenom-ena together with the possibil…
