Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

We report on the formation of heteronuclear quantum droplets in an attractive bosonic
mixture of K 41 and Rb 87. We observe long-lived self-bound states, both in free space and …

Quasicrystals are long-range ordered and yet nonperiodic. This interplay results in a wealth
of intriguing physical phenomena, such as the inheritance of topological properties from …

We produce Bose-Einstein condensates of two different species, Rb 87 and K 41, in an
optical dipole trap in proximity of interspecies Feshbach resonances. We discover and …

Building on the recent experimental observation with ultracold atoms, we report the first
experimental evidence of Efimov physics in a heteronuclear system. A mixture of K 41 and …

The bulk–boundary correspondence, a fundamental principle relating the topological
invariants of the bulk to the presence of edge states, is modified in periodically driven …

Recent measurements of Efimov resonances for a number of ultracold atom species have
revealed an unexpected universality, in which three-body scattering properties are …

We present the production of dual-species Bose-Einstein condensates (BECs) of K 39 and
Rb 87. Preparation of both species in the F= 1, m F=− 1 state enabled us to exploit a total of …

We report on the production of a 41 K-87 Rb dual-species Bose–Einstein condensate with
tunable interspecies interaction and we study the mixture in the attractive regime; ie, for …

We report on the production of a K 41-Rb 87 dual-species Bose-Einstein condensate in a
hybrid trap, consisting of a magnetic quadrupole and an optical dipole potential. After …
