Shift of the Bose-Einstein condensation transition in the presence of a second atomic species
Pedro M. Gaspar, Vanderlei S. Bagnato, Patricia C. M. Castilho
Atomic interactions play an important role in the properties of ultracold atomic gases. In single component bosonic systems, its effect is already present at the critical point for…
Characterization of nonequilibrium states of trapped Bose-Einstein condensates
V. I. Yukalov, A. N. Novikov, V. S. Bagnato
Generation of different nonequilibrium states in trapped Bose-Einstein condensates is studied by numerically solving nonlinear Schrodinger equation. Inducing nonequilibrium states…
Thermodynamic measurement of the sound velocity of a Bose gas across the transition to Bose-Einstein condensation
A. R. Fritsch, P. E. S. Tavares, F. A. J. Vivanco +3
We present an alternative method for determining the sound velocity in atomic Bose-Einstein condensates, based on thermodynamic global variables. The total number of trapped atoms…
Quantum turbulence in trapped atomic Bose-Einstein condensates
Marios C. Tsatsos, Pedro E. S. Tavares, Andre Cidrim +5
Turbulence, the complicated fluid behavior of nonlinear and statistical nature, arises in many physical systems across various disciplines, from tiny laboratory scales to geophysic…
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…
Generation of nonground-state Bose-Einstein condensates by modulating atomic interactions
E. R. F. Ramos, E. A. L. Henn, J. A. Seman +5
A technique is proposed for creating nonground-state Bose-Einstein condensates in a trapping potential by means of the temporal modulation of atomic interactions. Applying a time-d…
