Radio-frequency evaporation in an optical dipole trap
Raphael Lopes
We present an evaporative cooling technique for atoms trapped in an optical dipole trap that benefits from narrow optical transitions. For an appropriate choice of wavelength and p…
Many-body Decay of the Gapped Lowest Excitation of a Bose-Einstein Condensate
Jinyi Zhang, Christoph Eigen, Wei Zheng +7
We study the decay mechanism of the gapped lowest-lying excitation of a quasi-pure box-trapped atomic Bose-Einstein condensate. Owing to the absence of lower-energy modes, or direc…
Probing chiral edge dynamics and bulk topology of a synthetic Hall system
Thomas Chalopin, Tanish Satoor, Alexandre Evrard +4
Quantum Hall systems are characterized by the quantization of the Hall conductance -- a bulk property rooted in the topological structure of the underlying quantum states. In conde…
Probing quantum criticality and symmetry breaking at the microscopic level
Vasiliy Makhalov, Tanish Satoor, Alexandre Evrard +3
We report on an experimental study of the Lipkin-Meshkov-Glick model of quantum spins interacting at infinite range in a transverse magnetic field, which exhibits a ferromagnetic p…
From single-particle excitations to sound waves in a box-trapped atomic Bose-Einstein condensate
Samuel J. Garratt, Christoph Eigen, Jinyi Zhang +5
We experimentally and theoretically investigate the lowest-lying axial excitation of an atomic Bose-Einstein condensate in a cylindrical box trap. By tuning the atomic density, we…
Synthetic dissipation and cascade fluxes in a turbulent quantum gas
Nir Navon, Christoph Eigen, Jinyi Zhang +6
Scale-invariant fluxes are the defining property of turbulent cascades, but their direct measurement is a notorious problem. Here we perform such a measurement for a direct energy…
