Spontaneous Scalarization and its Application to the Holographic QCD Theory

• Hong Guo (IBS CTPU-PTC)

Room: B438 I would like to briefly introduce the phenomenon of spontaneous scalarization of black holes, which provides a new mechanism to evade the no-hair theorem. Within a simplified Einstein–Maxwell–Dilaton (EMD) framework, we have investigated the scalarization of Reissner–Nordström black holes. In this model, two types of hairy black hole solutions can be identified: one induced by the scalar potential and another arising from non-minimal coupling. I will show that the improved EMD model, which indicates a first-order QCD phase transition, can be understood in terms of the transition between these two classes of hairy black hole states.

Extra Dimension and 4D Effective Theory

• Yusuke Yamada (IBS CTPU-CGA (YSF))

Room: B438 I will briefly introduce the higher dimensional spacetime theory and how our 4D spacetime effectively emerges from it. Then, I discuss the possibility of the production of Kaluza-Klein particles in the early universe, which may become super heavy dark matter.
