It is a pleasure and an honor for the authors to respectfully dedicate this paper to David Sherrington, with admiration for his profound, wide-ranging and inspiring scientific contributions. One of the authors (PMG) wishes to express (or, better still, re-express – see Ref. [27]) his deep and abiding personal gratitude to David for his generous encouragement and warm friendship, beginning nearly three decades ago. The authors gratefully acknowledge support from awards DOE DE-FG02-07ER46453 (SG) and NSF DMR 09-06780 (PMG), as well as from the David and Lucille Packard Foundation (BLL).

N2 - Photons in multimode optical cavities can be used to mediate tailored interactions between atoms confined in the cavities. For atoms possessing multiple internal (i.e., "spin") states, the spin-spin interactions mediated by the cavity are analogous in structure to the Ruderman-Kittel-Kasuya- Yosida (RKKY) interaction between localized spins in metals. Thus, in particular, it is possible to use atoms in cavities to realize models of frustrated and/or disordered spin systems, including models that can be mapped on to the Hopfield network model and related models of associative memory. We explain how this realization of models of associative memory comes about and discuss ways in which the properties of these models can be probed in a cavity-based setting.
