A tunable SU(2) gauge field has been realized experimentally in a Raman momentum lattice using ultracold atoms. The chiral dynamics of the system have been investigated under different gauge potentials, whose non-Abelian nature was confirmed through observation of the non-Abelian Aharonov–Bohm effect.

Topological insulators exhibit unidirectional flow of robust electric charge at the edge of the system. Two recent experiments have observed these chiral edge modes in exceptionally controllable settings of ultracold atoms.

By smashing protons together at blinding speeds, scientists have shown that pairs of quarks display the phenomenon of quantum entanglement. The result could lead to fresh insight about one of the forces holding nuclei together.

Rydberg atoms in optical tweezers are a promising platform for quantum information science. A platform composed of dual-species Rydberg arrays has been realized, offering access to unexplored interaction regimes and crosstalk-free midcircuit control.

Asteroid tracking has been demonstrated as a promising and prominent probe of fifth forces arising in several well-motivated models beyond the Standard Model of particle physics. The authors use the state-of-art tracking data for the asteroid Bennu from the OSIRIS-REx mission to derive the tightest limits on fifth forces and ultralight dark matter at the lengths of solar-system objects.

Approximate notions of quantum error-correcting codes hold wide importance across quantum information and physics, but are not cohesively understood. Now, general rigorous connections established between approximate quantum error correction and quantum circuit complexity reveal a ‘complexity phase diagram’ for generalized quantum codes — and create a new unifying lens on complex quantum systems.

Dimensionality tuning can control fluctuations and induce complex phase diagrams with multiple orders and transitions among them. Now, experiments demonstrate intertwined vestigial order in the two- to three-dimensional crossover region in a van der Waals magnet.

Swirling magnetic structures move through a material in ways that depend on their interactions with mobile electrons. Fresh insight into how to control this electrodynamic effect could lead to ultracompact magnetic devices.
