Mean field theory for strongly coupled systems: Holographic approach
Supalert Sukrakarn, Taewon Yuk, Sang-Jin Sin
In this paper, we develop the holographic mean field theory for strongly interacting fermion systems. We investigate various types of the symmetry-breakings and their effect on the…
First order phase transition in the D3-D7 model from the point of view of the fermionic spectral functions
Xian-Hui Ge, Shuta Ishigaki, Sang-Jin Sin +1
We consider the D3-D7 model and use the spectral function of a probe fermion on D7 to analyze the first order phase transition from the black-hole embedding phase to another black-…
Order parameter and spectral function in -wave holographic superconductors
Debabrata Ghorai, Taewon Yuk, Sang-Jin Sin
We consider the -wave holographic superconductor model with full backreaction on the metric, addressing a missing part in the literature. We have identified the corrected order…
Fermi arc in -wave holographic superconductors
Debabrata Ghorai, Taewon Yuk, Sang-Jin Sin
We have investigated the fermionic spectral function in -wave holographic superconductors. We show that the vector model with minimal coupling reveals a -wave spectral functi…
Observation of Kondo condensation in a degenerately doped silicon metal
H. Im, D. U. Lee, Y. Jo +10
When a magnetic moment is embedded in a metal, it captures itinerant electrons to form the Kondo cloud1,2, which can spread out over a few micrometres3,4. For a metal with dense ma…
