Exact Finite- eRS Surface-Defect Indices and Giant-Graviton Corrections in SYM
Ji-Seong Chae
We compute the exact finite-\(N\) superconformal index of four-dimensional \(\mathcal N=4\) \(U(N)\) Yang--Mills theory with antisymmetric elliptic Ruijsenaars--Schneider (eRS) sur…
Holographic Entanglement Anisotropy as a Dark Deformation RG Probe in Hyperscaling-Violating -Wave Superfluids
Ji-Seong Chae
We study dark-sector deformations of anisotropic \(p\)-wave superfluids in hyperscaling-violating black-brane backgrounds, where the visible non-Abelian sector condenses a vector o…
Covariant Holographic Entanglement Entropy Inversion to Reconstruct Bulk Geometry
Ji-Seong Chae
We derive an analytic inverse map from the renormalized covariant interval entropy to a symmetry-reduced stationary bulk metric. The main result applies to stationary homogeneous a…
Perturbative Nicolai-Map Diagrammatics: Application to Poincaré Supergravity
Ji-Seong Chae, Hun Jang, Junhyeok Lee
We develop a perturbative, diagrammatic framework for constructing Nicolai maps and apply it to four-dimensional Poincaré supergravity expanded around flat Minkows…
Momentum-space Langevin dynamics of holographic Wilsonian RG flow: self-interacting massive scalar field theory
Ji-seong Chae, Jae-Hyuk Oh
We explore mathematical relationship between holographic Wilsonian renormalization group(HWRG) and stochastic quantization(SQ) motivated by the similarity of the monotonicity in RG…
