  Living cells exhibit multi-mode transport that switches between an active,
self-propelled motion and a seemingly passive, random motion. Cellular
decision-making over transport mode switching is a stochastic process that
depends on the dynamics of the intracellular chemical network regulating the
cell migration process. Here, we propose a theory and an exactly solvable model
of multi-mode active matter. Our exact model study shows that the reversible
transition between a passive mode and an active mode is the origin of the
anomalous, super-Gaussian transport dynamics, which has been observed in
various experiments for multi-mode active matter. We also present the
generalization of our model to encompass complex multi-mode matter with
arbitrary internal state chemical dynamics and internal state dependent
transport dynamics.
