Kaluza-Klein ansatz from Lorentzian quantum gravity on the fuzzy sphere
Chengcheng Liu, Shahn Majid
If Kaluza-Klein ideas were correct as an explanation of Yang-Mills and General Relativity on spacetime, the extra fibre geometry would have to be a sphere of constant size of the o…
Fermions in the fuzzy sphere Kaluza-Klein model
Chengcheng Liu, Shahn Majid
We consider spinors on the total space of a Kaluza-Klein model with fuzzy sphere fibre and geometrically realised Dirac operator on the product. We show that a single massless spin…
Yang-Mills field from fuzzy sphere quantum Kaluza-Klein model
Chengcheng Liu, Shahn Majid
Using the framework of quantum Riemannian geometry, we show that gravity on the product of spacetime and a fuzzy sphere is equivalent under minimal assumptions to gravity on spacet…
Quantum Kaluza-Klein theory with
Chengcheng Liu, Shahn Majid
Following steps analogous to classical Kaluza-Klein theory, we solve for the quantum Riemannian geometry on in terms of classical Riemannian ge…
Quantum geodesics on -Minkowski spacetime
Chengcheng Liu, Shahn Majid
We apply a recent formalism of quantum geodesics to the well-known bicrossproduct model -Minkowski quantum spacetime with its flat quantum metric as a mo…
Overcharging magnetized black holes at linear order and the weak cosmic censorship conjecture
Chengcheng Liu, Sijie Gao
Evidences have been found that the weak cosmic censorship conjecture could be violated if test particles with charge and angular momentum are injected into a black hole. However, s…
Switchback effect of holographic complexity in multiple-horizon black holes
Jie Jiang, Zhaohui Chen, Chengcheng Liu
In this paper, we use the "complexity equals action" (CA) conjecture to explore the switchback effect in the strongly-coupled quantum field theories with finite and finite coup…
