Doped Holographic Superconductors in Gubser-Rocha model
Ziyi Zhao, Wenhe Cai, Shuta Ishigaki
We construct a doped holographic superconductor in the Gubser-Rocha model, and realize a superconducting dome in the middle of the temperature-doping phase diagram. It is worth not…
Non-Hermitian quantum system generated from two coupled Sachdev-Ye-Kitaev models
Wenhe Cai, Sizheng Cao, Xian-Hui Ge +2
We show that a non-Hermitian two coupled Sachdev-Ye-Kitaev (SYK) model can provide thermodynamic structure equivalent to Hermitian two coupled SYK model. The energy spectrum, the e…
Heun's equation and analytic structure of the Gap in Holographic superconductivity
Yoon-Seok Choun, Wenhe Cai, Sang-Jin Sin
We present the new method to calculate the critical temperature as a function of , conformal dimension of the cooper operator. We find that, in the regime where th…
The superconducting dome for holographic doped Mott insulator with hyperscaling violation
Wenhe Cai, Sang-Jin Sin
We reconsider the holographic model featuring a superconducting dome on the temperature-doping phase diagram with a modified view on the role of the two charges. The first type cha…
Sound modes and stability of momentum dissipated black branes in holography
Wenhe Cai, Xian-Hui Ge, QingBing Wang
We systematically investigate the sound modes of momentum dissipated holographic systems. In particular, we focus on the Einstein-linear axions and the Einstein-Maxwell-dilaton-axi…
Holographic three flavor baryon in the Witten-Sakai-Sugimoto model with the D0-D4 background
Wenhe Cai, Si-wen Li
With the construction of the Witten-Sakai-Sugimoto model in the D0-D4 background, we systematically investigate the holographic baryon spectrum in the case of three flavors. The ba…
Diffusion in higher dimensional SYK model with complex fermions
Wenhe Cai, Xian-Hui Ge, Guo-Hong Yang
We construct a new higher dimensional SYK model with complex fermions on bipartite lattices. As an extension of the original zero-dimensional SYK model, we focus on the one-dimensi…
Electromagnetic instability and Schwinger effect in the Witten-Sakai-Sugimoto model with D0-D4 background
Wenhe Cai, Kang-le Li, Si-wen Li
Using the Witten-Sakai-Sugimoto model in the D0-D4 background, we holographically compute the vacuum decay rate of the Schwinger effect in this model. Our calculation contains the…
Sound waves in the compactified D0-D4 brane system
Wenhe Cai, Si-wen Li
As an extension to our previous work, we study the transport properties of the Witten-Sakai-Sugimoto model in the black D4-brane background with smeared D0-branes (D0-D4/D8 system)…
On the Elliptic Genus of Three E-strings and Heterotic Strings
Wenhe Cai, Min-xin Huang, Kaiwen Sun
A precise formula for the elliptic genus of three E-strings is presented. The related refined free energy coincides with the result calculated from topological string on local half…
Baryons in the Sakai-Sugimoto model in the D0-D4 background
Wenhe Cai, Chao Wu, Zhiguang Xiao
The baryon spectrum in the Sakai-Sugimoto model in the D4 background with smeared D0 charges is studied. We follow the instanton description of baryons by Hata et al.[Prog. Theor.…
