Abstract
The role of fermionic matter in the spectrum of the area operator is analyzed using the Baez--Krasnov framework for quantum fermions and gravity. The result is that the fermionic contribution to the area of a surface is equivalent to the contribution of purely gravitational spin network's edges tangent to . Therefore, the spectrum of the area operator is the same as in the pure gravity case.
