Dynamics of feedback Ising model
Yi-Ping Ma, Ivan Sudakow, P. L. Krapivsky +1
We study the dynamics of a mean-field Ising model whose coupling depends on the magnetization via a linear feedback function. A key feature of this linear feedback Ising model (FIM…

Mixed phases in feedback Ising models
Yi-Ping Ma, Ivan Sudakow, P. L. Krapivsky
We study mean-field Ising models in which the coupling depends on the magnetization via a feedback function. We identify mixed phases (MPs) and show that they can be stable at zero…
