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…

Non-Perturbative Renormalization Group for Ising-Nematic Criticality: A Closed-Form Nonlocal Ansatz

Hyeon Jung Kim, Kyoung-Min Kim, Ki-Seok Kim

The two-dimensional metallic quantum critical problem is a long-standing puzzle that is widely believed to hold the key to resolving ubiquitous non-Fermi liquid behavior in strongl…

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…

Microscopic origin of local electric polarization in NiPS

Hyeon Jung Kim, Ki-Seok Kim

Recently, Zhang-Rice triplet to singlet excitations have been measured experimentally and verified numerically in a van der Waals antiferromagnet NiPS\textsubscript{3}, which revea…
