Understand

We propose a new realization of axion monodromy inflation in which axion monodromy arises from torsional cycles in a type IIB compactification.

A class of monomial potentials is obtained with specific values for the power index.
Moreover, the inflaton mass changes profile due to the couplings between various fields after compactification.
Consequently, the potential obtains a step-like profile at some critical scale.
