I will show the results of QCD equation of state under finite temperature, finite baryon density and fast rotation in the framework of dynamical holographic QCD model, and comparing with lattice QCD calculations.
We show that the dynamics of entanglement entropy in CFT are precisely Einstein equation. The QFT RG equation turns out to be a geometric identity. In the entropy generated geometry, a covariant Klein-Gordon equation is also found. We are thus led to propose some new interpretation about Gauge/Gravity duality.
In holographic systems with large N, the hydrodynamic derivative expansion converges in momentum space. However, the first subleading effect in the 1/N expansion results in a long-time tail in the hydrodynamic response, leading to breakdown of the derivative expansion. This talk explores how these subleading corrections can be systematically incorporated by modifying the derivative expansion,...
Recently there has been growing interest in spin polarization in relativistic heavy ion collisions. It is known that spin can be induced by different hydrodynamic gradients. So far most theoretical frameworks for spin polarization is based on quasi-particles, which leads to the understanding that spin polarization comes from modified distribution and modified fluctuation-dissipation relation....
I will explain what a spin current is, why it is important in describing heavy ion collisions, and why a holographic spin current would be useful. I will then describe the challenges in constructing a holographic spin current and how they are addressed.
We calculate holographic thermal correlators using a recurrence relation of $\{a_n\}$ at $n\to\infty$, building on recent advances in the connection formula for the Heun equation. We consider two gravitational solutions that correspond to distinct states in different subsectors of $\mathcal{N}=4$ super-Yang-Mills theory at finite temperature and density. The first solution is the...
Bulk reconstruction in the AdS/CFT correspondence is aimed to construct the bulk gravity from the information of the boundary CFT. While the fine structure of entanglement are quantities which can unravel more refined infromation about the quantum entanglement. In this talk, we will introduce our recent works on these two topics and will show that the fine structure of entanglement, such as...
For black holes, we apply the Seiberg-Witten (SW)/Quasinormal Modes (QNM) correspondence to analytically calculate the black hole QNM and superradiance frequencies. For neutron stars, two types of holographic QCD is used to extract the equation of state. We then discuss the gravitational wave observation interpretations and restrictions on those compact star models.
In this talk, I will introduce our recent works on the application of machine learning in the holographic QCD. Using the machine learning, we can construct the holographic model with lattice EOS. We calculated the heavy quark potential, jet queching parameters and so on based on our model. Combining the machine learning with hadron spectrum, we can also construct the holographich model which...
