Bright soliton to quantum droplet transition in a mixture of Bose-Einstein condensates
P. Cheiney, C. R. Cabrera, J. Sanz +3
Attractive Bose-Einstein condensates can host two types of macroscopic self-bound states of different nature: bright solitons and quantum liquid droplets. Here, we investigate the…
Quantum liquid droplets in a mixture of Bose-Einstein condensates
C. R. Cabrera, L. Tanzi, J. Sanz +4
Quantum droplets are small clusters of atoms self-bound by the balance of attractive and repulsive forces. Here we report on the observation of a novel type of droplets, solely sta…
Dipolar atomic spin ensembles in a double-well potential
A. de Paz, B. Naylor, J. Huckans A. Carrance +5
We experimentally study the spin dynamics of mesoscopic ensembles of ultracold magnetic spin-3 atoms located in two separated wells of an optical dipole trap. We use a radio-freque…
Spin mixing and protection of ferromagnetism in a spinor dipolar condensate
S. Lepoutre, K. Kechadi, B. Naylor +7
We study spin mixing dynamics in a chromium dipolar Bose-Einstein Condensate, after tilting the atomic spins by an angle with respect to the magnetic field. Spin mixing is tri…
A chromium dipolar Fermi sea
B. Naylor, A. Reigue, E. Maréchal +3
We report on the production of a degenerate Fermi gas of 53Cr atoms, polarized in the state F=9/2, m_F=-9/2, by sympathetic cooling with bosonic S=3, m_S=-3 52Cr atoms. We load in…
Exploring out-of-equilibrium quantum magnetism and thermalization in a spin-3 many-body dipolar lattice system
S. Lepoutre, J. Schachenmayer, L. Gabardos +7
Understanding quantum thermalization through entanglement build-up in isolated quantum systems addresses fundamental questions on how unitary dynamics connects to statistical physi…
High Spectral Resolution Measurement of the Sunyaev-Zel'dovich Effect Null with Z-Spec
M. Zemcov, J. Aguirre, J. Bock +15
The Sunyaev-Zel'dovich (SZ) effect spectrum crosses through a null where dT_CMB = 0 near nu_0 = 217 GHz. In a cluster of galaxies, nu_0 can be shifted from the canonical thermal SZ…
