Precision Measurements of Atom-Dimer Interactions in a Uniform Planar Bose Gas
C. Maury, B. Bakkali-Hassani, G. Chauveau +4
Cold quantum gases, when acted upon by electromagnetic fields, can give rise to samples where isolated atoms coexist with dimers or trimers, which raises the question of the intera…
Townes soliton and beyond: Non-miscible Bose mixtures in 2D
Brice Bakkali-Hassani, Jean Dalibard
In these lecture notes, we discuss the physics of a two-dimensional binary mixture of Bose gases at zero temperature, close to the point where the two fluids tend to demix. We are…
The cross-over from Townes solitons to droplets in a 2D Bose mixture
B. Bakkali-Hassani, C. Maury, S. Stringari +3
When two Bose-Einstein condensates -- labelled 1 and 2 -- overlap spatially, the equilibrium state of the system depends on the miscibility criterion for the two fluids. Here, we 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…
Tan's two-body contact across the superfluid transition of a planar Bose gas
Y. -Q. Zou, B. Bakkali-Hassani, C. Maury +4
Tan's contact is a quantity that unifies many different properties of a low-temperature gas with short-range interactions, from its momentum distribution to its spatial two-body co…
Magnetic dipolar interaction between hyperfine clock states in a planar alkali Bose gas
Y. -Q. Zou, B. Bakkali-Hassani, C. Maury +4
In atomic systems, clock states feature a zero projection of the total angular momentum and thus a low sensitivity to magnetic fields. This makes them widely used for metrological…
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…
