Title |
Holographic entanglement entropy from random tensor networks via group field theory |
|
Abstract |
We investigate the use of tensor networks techniques and quantum
information theory for the study of the entanglement properties of quantum
geometry states. In the language of the group field theory, we describe
spin network states as quantum many-body systems. The very connectivity of
such states, encoded in the links of the underlying graphs, is associated
with the entanglement between the fundamental quanta constituting them. We
establish a dictionary between group field theory states and (generalised)
random tensor networks. With such a dictionary at hand, we target the
calculation of the Ryu-Takayanagi formula for the entanglement entropy in
the quantum gravity formalism of group field theory. |
