Matter in Loop Quantum Gravity

Understand

Loop quantum gravity, a non-perturbative and manifestly background free, quantum theory of gravity implies that at the kinematical level the spatial geometry is discrete in a specific sense.

• The spirit of background independence also requires a non-standard quantum representation of matter.
• While loop quantization of standard model fields has been proposed, detail study of its implications is not yet available.
• This review aims to survey the various efforts and results.
