Isothermal compressibility determination across Bose-Einstein condensation
F. J. Poveda-Cuevas, P. C. M. Castilho, E. D. Mercado-Gutierrez +5
We apply the global thermodynamic variables approach to experimentally determine the isothermal compressibility parameter of a trapped Bose gas across the phase transition. W…
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…
Route to turbulence in a trapped Bose-Einstein condensate
J. A. Seman, E. A. L. Henn, R. F. Shiozaki +8
We have studied a Bose-Einstein condensate of atoms under an oscillatory excitation. For a fixed frequency of excitation, we have explored how the values of amplitude and…
Three-vortex configurations in trapped Bose-Einstein condensates
J. A. Seman, E. A. L. Henn, M. Haque +9
We report on the creation of three-vortex clusters in a Bose-Einstein condensate by oscillatory excitation of the condensate. This procedure can create vortices of both c…
Cooling atoms in an optical trap by selective parametric excitation
N. Poli, R. J. Brecha, G. Roati +1
We demonstrate the possibility of energy-selective removal of cold atoms from a tight optical trap by means of parametric excitation of the trap vibrational modes. Taking advantage…
