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…
Conserved Quantities and the Algebra of Braid Excitations in Quantum Gravity
Song He, Yidun Wan
We derive conservation laws from interactions of braid-like excitations of embedded framed spin networks in Quantum Gravity. We also demonstrate that the set of stable braid-like e…
A covariant entropy bound conjecture on the dynamical horizon
Song He, Hongbao Zhang
As a compelling pattern for the holographic principle, our covariant entropy bound conjecture is proposed for more general dynamical horizons. Then we apply our conjecture to CD…
Helicity Entanglement of Moving Bodies
Shuxin Shao, Song He, Hongbao Zhang
We investigate the Lorentz transformation of the reduced helicity density matrix for a pair of massive spin 1/2 particles. The corresponding Wootters concurrence shows no invariant…
