Coexisting Regular and Chaotic Dynamics in the Dysprosium Feshbach Spectrum
Julie Veschambre, Alexandre Journeaux, Maxime Lecomte +7
Strongly dipolar gases, such as dysprosium, erbium and thulium, exhibit dense Feshbach spectra whose level statistics have been associated with quantum chaos arising from couplings…
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…
Miscibility regimes in a Na-K quantum mixture
Emmanuel M. Gutierrez, Gustavo A. de Oliveira, Kilvia M. Farias +2
Effects of miscibility in interacting two-component classical fluids are relevant in a broad range of daily applications. When considering quantum systems, two-component Bose-Einst…
Universal dynamics of a turbulent superfluid Bose gas
A. D. García-Orozco, L. Madeira, M. A. Moreno-Armijos +6
We study the emergence of universal scaling in the time-evolving momentum distribution of a harmonically trapped three-dimensional Bose-Einstein condensate, parametrically driven t…
Realization of a Townes soliton in a two-component planar Bose gas
B. Bakkali-Hassani, C. Maury, Y. -Q. Zou +6
Most experimental observations of solitons are limited to one-dimensional (1D) situations, where they are naturally stable. For instance, in 1D cold Bose gases, they exist for any…
Optical control of the density and spin spatial profiles of a planar Bose gas
Y. -Q. Zou, É. Le Cerf, B. Bakkali-Hassani +7
We demonstrate the arbitrary control of the density profile of a two-dimensional Bose gas by shaping the optical potential applied to the atoms. We use a digital micromirror device…
Dynamical symmetry and breathers in a two-dimensional Bose gas
Raphaël Saint-Jalm, Patricia C. M. Castilho, Édouard Le Cerf +5
A fluid is said to be \emph{scale-invariant} when its interaction and kinetic energies have the same scaling in a dilation operation. In association with the more general conformal…
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…
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…
Measurement of the mobility edge for 3D Anderson localization
Giulia Semeghini, Manuele Landini, Patricia Castilho +6
Anderson localization is a universal phenomenon affecting non-interacting quantum particles in disorder. In three spatial dimensions it becomes particularly interesting to study be…
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…
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…
