High-capacity associative memory in a quantum-optical spin glass
Brendan P. Marsh, David Atri Schuller, Yunpeng Ji +5
The Hopfield model describes a neural network that stores memories using all-to-all-coupled spins. Memory patterns are recalled under equilibrium dynamics. Storing too many pattern…

A multimode cavity QED Ising spin glass
Brendan P. Marsh, David Atri Schuller, Yunpeng Ji +5
We realize a driven-dissipative Ising spin glass using cavity QED in a novel ``4/7" multimode geometry. Gases of ultracold atoms trapped within the cavity by optical tweezers serve…

Directly observing replica symmetry breaking in a vector quantum-optical spin glass
Ronen M. Kroeze, Brendan P. Marsh, David Atri Schuller +6
Spin glasses are quintessential examples of complex matter. Although much about their order remains uncertain, abstract models of them inform, e.g., the classification of combinato…
