Quantum States of Fields for Quantum Split Sources
Lin-Qing Chen, Flaminia Giacomini, Carlo Rovelli
Field mediated entanglement experiments probe the quantum superposition of macroscopically distinct field configurations. We show that this phenomenon can be described by using a t…
Bulk amplitude and degree of divergence in 4d spin foams
Lin-Qing Chen
We study the 4-d holomorphic Spin Foam amplitude on arbitrary connected 2-complexes and degrees of divergence. With recently developed tools and truncation scheme, we derive a form…
A simpler way of imposing simplicity constraints
Andrzej Banburski, Lin-Qing Chen
We investigate a way of imposing simplicity constraints in a holomorphic Spin Foam model that we recently introduced. Rather than imposing the constraints on the boundary spin netw…
Pachner moves in a 4d Riemannian holomorphic Spin Foam model
Andrzej Banburski, Lin-Qing Chen, Laurent Freidel +1
In this work we study a Spin Foam model for 4d Riemannian gravity, and propose a new way of imposing the simplicity constraints that uses the recently developed holomorphic represe…
Orientability of loop processes in relative locality
Lin-Qing Chen
Inspired by recent results of unusual properties of loop processes in relative locality, we introduce a way to classify loops in the case of kappa-Poincare momentum space. We show…
Causal loop in the theory of relative locality
Lin-Qing Chen
We find that relative locality, a recently proposed Planck-scale deformation of special relativity, suffers from the existence of causal loops. A simple and general construction of…
