Fuchsian Resonance and a Horizon-to-Boundary Dictionary for Pole-Skipping
Yoon-Seok Choun
Pole-skipping occurs at special complex frequencies and momenta where the retarded Green function of a black-hole or black-brane background is not uniquely defined. The local near-…
A Horizon-to-Boundary Dictionary Linking Smooth Horizon Continuation, Pole-Skipping, and Lowest-Weight Structure
Yoon-Seok Choun, Ki-Seok Kim
We study pole-skipping for a scalar field in the JT/AdS black-hole background. Previous work established the local mechanism: at a pole-skipping point, a near-horizon recurrenc…
Holographic dual effective field theory in the Luttinger-Ward functional approach: Application to an SYK model
Yoon-Seok Choun, Hyeon Jung Kim, Ki-Seok Kim
We construct an emergent holographic dual description in the Luttinger-Ward functional approach, where the renormalization group (RG) flows of collective bi-local fields appear man…
Quantum Scaling Dimension from the Equivalence principle
Yoon-Seok Choun, Ki-Seok Kim, Sang-Jin Sin
We propose a method to constrain the scaling dimension of the operators of the strongly interacting systems (SIS) using the holographic setup. %where the (d+1)-dimensional black ho…
Renormalization group flow to effective quantum mechanics at IR in an emergent dual holographic description for spontaneous chiral symmetry breaking
Ki-Seok Kim, Mitsuhiro Nishida, Yoonseok Choun
Implementing the Wilsonian renormalization group (RG) transformation in a nonperturbative way, we construct an effective holographic dual description with an emergent extradimensio…
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…
Scaling dimension of Cooper pair operator from the black hole interior
Yoon-Seok Choun, Sang-Jin Sin
We have shown that in holographic superconductivity theory for 3+1 dimensional system, the scaling dimension of Cooper pair operator can be obtained as a quantized value if we requ…
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…
Bridging the Chiral symmetry and Confinement with Singularity
Yoon-Seok Choun, Sang-Jin Sin
We consider a holographic quark model where the confinement is a consequence of the quark condensate. Surprisingly, the equation of motion of our holographic model can be mapped to…
