Entanglement Entropy of Topological Orders with Boundaries
Chaoyi Chen, Ling-Yan Hung, Yingcheng Li +1
In this paper we explore how non trivial boundary conditions could influence the entanglement entropy in a topological order in 2+1 dimensions. Specifically we consider the special…
Revisiting Entanglement Entropy of Lattice Gauge Theories
Ling-Yan Hung, Yidun Wan
Casini et al raise the issue that the entanglement entropy in gauge theories is ambiguous because its definition depends on the choice of the boundary between two regions.; even a…
Emergent Braided Matter of Quantum Geometry
Sundance Bilson-Thompson, Jonathan Hackett, Louis Kauffman +1
We review and present a few new results of the program of emergent matter as braid excitations of quantum geometry that is represented by braided ribbon networks. These networks ar…
Infinite Degeneracy of States in Quantum Gravity
Jonathan Hackett, Yidun Wan
The setting of Braided Ribbon Networks is used to present a general result in spin-networks embedded in manifolds: the existence of an infinite number of species of conserved quant…
Effective Theory of Braid Excitations of Quantum Geometry in terms of Feynman Diagrams
Yidun Wan
We study interactions amongst topologically conserved excitations of quantum theories of gravity, in particular the braid excitations of four-valent spin networks. These have been…
C, P, and T of Braid Excitations in Quantum Gravity
Song He, Yidun Wan
We study the discrete transformations of four-valent braid excitations of framed spin networks embedded in a topological three-manifold. We show that four-valent braids allow seven…
