What is Extended Fisher-Kolmogorov (EFK)?

There are many references to it, but I failed to find what is actually is. Is it some kind of non-linear differential equation? Does it describe physical systems?

Short answer would be:

It is a nonlinear PDE, usually stated as

$$u_t+\gamma u_{xxxx}-u_{xx}-u+u^3=0 $$

as introduced in Dee & van Sarloos' paper. Most authors like to emphasize its application in modeling of phase transitions at critical points.
