Query: Quantum reduced loop gravity: extension to scalar field   The quantization of the Hamiltonian for a scalar field is performed in the
framework of Quantum Reduced Loop Gravity. We outline how the regularization
can be performed by using the analogous tools adopted in full Loop Quantum
Gravity and the matrix elements of the resulting operator between basis states
are analytic coefficients. These achievements open the way for a consistent
analysis of the Quantum Gravity corrections to the classical dynamics of
gravity in the presence of a scalar field in a cosmological setting.
