Entanglement entropy of coherent intertwiner in loop quantum gravity
Gaoping Long, Qian Chen, Jinsong Yang
In this paper, we carry out the entanglement calculations on the coherent intertwiners. We first consider the entanglement introduced by the group-averaging of the tensor-product t…

Graphical calculus of spin networks
Emanuele Alesci, Ilkka Mäkinen, Jinsong Yang
Graphical techniques provide a very useful practical device for calculations involving the so-called spin network states, which encode the quantum degrees of freedom of spatial geo…
