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…
Taming the 3D Wilson-Fisher Fixed Point via Nonlocal Effective Action
Hyeon Jung Kim, Seung-Jong Yoo, Jinmo Bok +3
We present a Renormalization Group (RG) framework based on a nonlocal effective action ansatz to analyze the strong coupling dynamics of the three-dimensional relativistic …
Emergent Geometry from Functional Renormalization Group via Bulk Metric Reconstruction
Hyeon Jung Kim, Ki-Seok Kim
We present a holographic dual description for the O(N) vector model in -dimensional Euclidean space within the functional renormalization group (FRG) framework. By iterating Wil…
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…
