Observation of vortex formation in an oscillating trapped Bose-Einstein condensate
E. A. L. Henn, J. A. Seman, E. R. F. Ramos +7
We report on the observation of vortex formation in a Bose-Einstein condensate of Rb-87 atoms. Vortices are generated by superimposing an oscillating excitation to the trapping pot…

Observation of Quantum Phase Transitions with Parity-Symmetry Breaking and Hysteresis
A. Trenkwalder, G. Spagnolli, G. Semeghini +8
Symmetry-breaking quantum phase transitions play a key role in several condensed matter, cosmology and nuclear physics theoretical models. Its observation in real systems is often…

Measuring The Heat Capacity in a Bose-Einstein Condensation using Global Variables
R. F. Shiozaki, G. D. Telles, P. Castilho +5
Phase transitions are well understood and generally followed by the behavior of the associated thermodynamic quantities, such as in the case of the point superfluid transition…
