An alternative Quantisation of the Flux Operator in Loop Quantum Gravity — •Kristina Giesel^1,2 and Thomas Thiemann^1,2 — ¹Albert-Einstein-Institut für Gravitationsphysik, Am Mühlenberg 1, 14476 Golm — ²Perimeter Institute for Theoretical Physics, 31 Caroline Street, Waterloo, Ontario N2L 2Y5, Canada

We will introduce an alternative way of quantising the flux operator that is usually used in Loop Quantum gravity (LQG). For this purpose we will use the same quantisation procedure that was used in quantising the Hamiltonian Constraint of LQG. In comparing the action of the alternative flux operator with the one of the usual flux operator, we can verify whether this quantisation procedure leads to the expected result.
