University of Illinois & Birmingham Build Active Gauge Field

Researchers from the University of Illinois at Urbana-Champaign and the University of Birmingham have experimentally realized a tuneable non-Abelian gauge field within an actively controlled mechanical lattice. The team encoded a local pseudo-spin for every lattice site using pairs of oscillators, with inter-site spin-dependent couplings engineered via real-time measurement and feedback, a novel approach that moves beyond electronic or optical simulations of complex physics. Crucially, the researchers experimentally extracted Wilson-loop observables, demonstrating the creation of…
