Holographic entanglement entropy probe on spontaneous symmetry breaking with vector order
Chanyong Park, Gitae Kim, Ji-seong Chae +1
We study holographic entanglement entropy in 5-dimensional charged black brane geometry obtained from Einstein-SU(2)Yang-Mills theory defined in asymptotically AdS space. This grav…
ABC-stacked multilayer graphene in holography
Jeong-Won Seo, Taewon Yuk, Young-Kwon Han +1
A flat band can be studied an infinitely strong coupling, realized in a simple system. Therefore, its holographic realization should be interesting. Laia and Tong gave a realizatio…
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…
Flow Equation and Fermion Gap in the Holographic Superconductors
Taewon Yuk, Sang-Jin Sin
We reconsider the fermion spectral function in the presence of the Cooper pair condensation and identified the interaction type of complex scalar and fermion, which gives consisten…
Holographic Lieb lattice and gapping its Dirac band
Young-Kwon Han, Jeong-Won Seo, Taewon Yuk +1
We first point out that the Laia-Tong model realizes the Lieb lattice in the holographic setup. It generates a flat band of sharp particle spectrum together with a Dirac band of un…
Momentum dependent gap in holographic superconductors revisited
Debabrata Ghorai, Yoon-Seok Choun, Sang-Jin Sin
We reconsider the angular dependence in gap structure of holographic superconductors, which has not been treated carefully so far. For the vector field model, we show that the norm…
