exact and numerical techniques that can be used for nanoscale devices with memory, including recent experiments on self-organizing nanowires.
A large body of work has shown that PVP-coated self-organizing Ag nanowires have a dynamic response to an applied voltage that mimics the
short-term plasticity of neuronal synapses. However, while every single experiment has a different connectivity pattern, it is observed a conductance
response that is not strongly dependent on the details of the nanowire network. In this talk, we use recent results on the study of memristive networks
that apply to dynamical systems with constraints, such as Kirchhoff laws, to derive a mean field theory for networks of nanowires. We
show how these mean field theories have potential applications that go beyond the specificity of the system, but that can be applied to a larger
class of dynamical systems.
