Towards a Carrollian Description of Yang-Mills
Jeffrey Opreij, David Skinner, Hangzhi Wang
We provide a theory defined purely on null infinity that describes Yang-Mills in the Minkowski space bulk. The dynamical field of our model is the characteristic data of the bulk g…
The Impact of Inhomogeneous Perturbations of the Inflaton on the Cosmological Primordial Magnetic Field
Yu Li, Shuang Liu, Hang Wang +1
We investigate the impact of inhomogeneous inflaton perturbations on primordial magnetic fields within the framework of generalized inflationary magnetogenesis models. Extending th…
The equivalence between Einstein and Jordan frames: a study based on the inflationary magnetogenesis model
Hang Wang, Shuang Liu, Yu Li +1
The equivalence of the Jordan and Einstein frames has been a subject of considerable interest in the field. In this paper, within the context of gravity, we explore the infl…
The merger of a black hole with a cosmological horizon
Maxime Gadioux, Hangzhi Wang
In recent years there have been many studies on exactly solvable black hole mergers, based on a model by Emparan and Martinez where the mass of one black hole is blown up to infini…
