Query: Realization of a Bosonic Antiferromagnet   Quantum antiferromagnets are of broad interest in condensed matter physics as
they provide a platform for studying exotic many-body states including spin
liquids and high-temperature superconductors. Here, we report on the creation
of a one-dimensional Heisenberg antiferromagnet with ultracold bosons. In a
two-component Bose-Hubbard system, we switch the sign of the spin-exchange
interaction and realize the isotropic antiferromagnetic Heisenberg model in an
extended 70-site chain. Starting from a low-entropy N\'eel-ordered state, we
use optimized adiabatic passage to approach the bosonic antiferromagnet. We
demonstrate the establishment of antiferromagnetism by probing the evolution of
the staggered magnetization and spin correlations of the system. Compared with
condensed matter systems, ultracold gases in optical lattices can be
microscopically engineered and measured, offering significant advantages for
exploring bosonic magnetism and spin dynamics.
