Frustration and Glassiness in Spin Models with Cavity-Mediated Interactions
Frustration and Glassiness in Spin Models with Cavity-Mediated Interactions
We show that the effective spin-spin interaction between three-level atoms confined in a multimode optical cavity is long-ranged and sign-changing, like the RKKY interaction; therefore, ensembles of such atoms subject to frozen-in positional randomness can realize spin systems having disordered and frustrated interactions. We argue that, whenever the atoms couple …
