ENTROPIC DYNAMICS: QUANTUM FIELD THEORY AND GRAVITY

The entropic dynamics approach to QFT is formulated for scalar fields in flat and curved background space-times, and also for dynamical space-times.

My interest in the exact Renormalization Group as a systematic way to choose the variables that are relevant to a particular physics problem goes back to my PhD thesis.

More recently, the connection between the RG and ED was explored in the following paper.
