We propose the generation of attosecond entangled biphotons in the extreme-ultraviolet regime by two-photon decay of a metastable atomic state as a source similar to spontaneous parametric down-conversion photons. The 1s2s ^{1}S_{0} metastable state

Spin-orbit coupling is interesting for fundamental understanding of spin transport and quench dynamics. Here the authors demonstrate spin-current generation and its relaxation in spin-orbit-coupled Bose-Einstein condensates of Rb atoms in different s

Scalable local control over gate operations is an outstanding challenge in the field of quantum computing and programmable quantum simulation with Rydberg-atom arrays. One approach is to use a global field to excite atoms to the Rydberg state and tun

The resonant profile of the rate coefficient for three-body recombination into a shallow dimer is investigated for mass-imbalanced systems. In the low-energy limit, three atoms collide with zero-range interactions, in a regime where the scattering le

Rydberg molecules have potential for ultracold chemistry applications in light of their unconventional binding mechanism that provides high tunability. Here the authors observe and control butterfly Rydberg molecules, which are bound by a shape reson

We observe spin transfer within a nondegenerate heteronuclear spinor atomic gas comprising a small ^{7}Li population admixed with a ^{87}Rb bath, with both elements in their F=1 hyperfine spin manifolds. Prepared in a nonequilibrium initial state, th

Within a dense environment (ρ≈10^{14} atoms/cm^{3}) at ultracold temperatures (T140 compared to 1 μs at n=90. In addition, a second observed reaction mechanism, namely, Rb_{2}^{+} molecule formation, was studied. Both reaction products are equall

Ultracold collisions of neutral atoms and molecules have been of great interest since experimental advances enabled the cooling and trapping of such species. This study develops a simplified theoretical treatment of a low-energy collision between an

Equal mass fermionic trimers with two different spin components near the unitary limit are shown to possess a universal van der Waals bound or resonance state near $s$-wave unitarity, when $p$-wave interactions are included between the particles with
