Events and their Localisation are Relative to a Lab

V. Vilasini, Lin-Qing Chen, Liuhang Ye +1

The notions of events and their localisation fundamentally differ between quantum theory and general relativity, reconciling them becomes even more important and challenging in the…

Measurement of non-Abelian gauge fields using multi-loop amplification

Qing-Xian Lv, Hong-Zhi Liu, Yan-Xiong Du +7

Non-Abelian gauge field (NAGF) plays a central role in understanding the geometrical and topological phenomena in physics. Here we experimentally induce a NAGF in the degenerate ei…

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…

Virasoro hair and entropy for axisymmetric Killing horizons

Lin-Qing Chen, Wan Zhen Chua, Shuwei Liu +2

We show that the gravitational phase space for the near-horizon region of a bifurcate, axisymmetric Killing horizon in any dimension admits a 2D conformal symmetry algebra with cen…

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…
