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…
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…
Doubly-dressed states for near-field trapping and subwavelength lattice structuration
Maxime Bellouvet, Caroline Busquet, Jinyi Zhang +3
We propose a scheme to tailor nanostructured trapping potentials for ultracold atoms. Our trapping scheme combines an engineered extension of repulsive optical dipole forces at sho…
