Entanglement entropy and monotones in scattering process
Jinbo Fan, Gao-Ming Deng, Xi-Jun Ren
In this paper, we study the entanglement property of a 4-particle system. In this system, two initially entangled electrons A and C are scattered by two uncorrelated positrons B an…
Fractional Skyrmion molecules in a model
Yutaka Akagi, Yuki Amari, Sven Bjarke Gudnason +2
We study fractional Skyrmions in a baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstab…
The moduli space of non-Abelian vortices in Yang-Mills-Chern-Simons-Higgs theory
Sven Bjarke Gudnason, Minoru Eto
We determine the dimension of the moduli space of non-Abelian vortices in Yang-Mills-Chern-Simons-Higgs theory in 2+1 dimensions for gauge groups $G=({\rm U}(1)\times G')/\mathbb{Z…
Effects of global monopole on critical behaviors and microstructure of charged AdS black holes
Gao-Ming Deng, Jinbo Fan, Xinfei Li
As an intriguing topological defect, global monopole's influence on behaviors of black holes has always been anticipated but still remains less clear. Analyzing the thermodynamics…
Near-BPS baby Skyrmions with Gaussian tails
Sven Bjarke Gudnason, Marco Barsanti, Stefano Bolognesi
We consider the baby Skyrme model in a physically motivated limit of reaching the restricted or BPS baby Skyrme model, which is a model that enjoys area-preserving diffeomorphism i…
