# Hubble constant

1. Homework Statement
If $$\phi$$ is a usual field is it possible that
$$H\dot{\phi}=-\partial^2\phi/{\partial x^2}$$
Where H is the hubble constant and the dot denotes time derivative

2. Homework Equations
$$H\dot{\phi}=-\partial^2\phi/{\partial x^2}$$

3. The Attempt at a Solution
I tried different ways but am not able to find the particular expression for hubble constant used here.
