Applicablilty of the Wheeler-DeWitt equation

  1. Jul 23, 2011 #1

    Throughout much of Carlo Rovelli's book "Quantum Gravity", he continually refers to the Wheeler DeWitt equation, but not always in the context of quantizing gravity. In his section on normal (quantum) field theory, he does a significant portion of the work around the Wheeler DeWitt equation with no reference to quantum gravity in the section. Is the Wheeler DeWitt equation applicable to other QFTs besides quantum gravity?

    Let me be even more specific, it seems to me that Rovelli implies that every equation of motion for any field theory can be written
    H\left( x^\alpha, \frac{\delta}{\delta x^\alpha}, \phi, \frac{\delta}{\delta \phi}\right)\Psi=0
