Tensor Network States


Tensor network states are used to describe physical states and processes in many-body physics and related disciplines. An explicit connection between these current methods and the diagrammatic methods known in category was made in the following paper.

Jacob Biamonte later taught a course explaining these results and exploring tensor networks in more detail.

Background reading

Vidal has written extensively about tensor networks, including:

Connection to spin networks and category theory

Vidal pointed out in


that tensor network states made of symmetric tensors were nothing but spin networks as used in loop quantum gravity. He suggests that this could lead to new interactions between different subjects. See also.
