Holographic two-point functions in medium
Chanyong Park, Se-Jin Kim, Jung Hun Lee
We study two-point correlation function in a medium composed of two kinds of matter, which is the dual of a three-dimensional generalized -brane gas geometry. Following the holo…
Dual Geometry of Entanglement Entropy via Deep Learning
Chanyong Park, Chi-Ok Hwang, Kyungchan Cho +1
For a given entanglement entropy of QFT, we investigate how to reconstruct its dual geometry by applying the Ryu-Takayanagi formula and the deep learning method. In the holographic…
The ideal intersection property for essential groupoid C*-algebras
Matthew Kennedy, Se-Jin Kim, Xin Li +2
We characterise, in several complementary ways, étale groupoids with locally compact Hausdorff space of units whose essential groupoid C*-algebra has the ideal intersection propert…
Nonunital operator systems and noncommutative convexity
Matthew Kennedy, Se-Jin Kim, Nicholas Manor
We establish the dual equivalence of the category of (potentially nonunital) operator systems and the category of pointed compact nc (noncommutative) convex sets, extending a resul…
The Hamilton-Jacobi Equation and Holographic Renormalization Group Flows on Sphere
Nakwoo Kim, Se-Jin Kim
We study the Hamilton-Jacobi formulation of effective mechanical actions associated with holographic renormalization group flows when the field theory is put on the sphere and mass…
On the progenitor quark mass matrix
Jihn E. Kim, Se-Jin Kim
We determined the quark mass matrix in terms of a small expansion parameter , which gives correctly all the quark masses and the CKM matrix elements at the elec…
Re-visiting Supersymmetric Janus Solutions: A Perturbative Construction
Nakwoo Kim, Se-Jin Kim
We construct holographic Janus solutions, which describe a conformal interface in the theory of M2-branes, in four-dimensional gauged supergravities using a perturbative method. In…
Tetrahedral Symmetry A in Anti-SU(5) GUT
Paul H. Frampton, Jihn E. Kim, Se-Jin Kim +1
We construct a flavor model in an anti-SU(5) GUT with a tetrahedral symmetry . We choose a basis where quarks and charged leptons are already mass eige…
Jarlskog determinant and data on flavor matrices
Jihn E. Kim, Se-Jin Kim, Soonkeon Nam +1
The essences of the weak CP violation, the quark and lepton Jarlskog invariants, are determined toward future model buildings beyond the Standard Model (SM). The equivalence of two…
Hyperrigidity of C*-correspondences
Se-Jin Kim
We show that hyperrigidity for a C*-correspondence is equivalent to non-degeneracy of the left action of the Katsura ideal on . Due to the work of Katsou…
A perturbative study of holographic mABJM theory
Nakwoo Kim, Se-Jin Kim
Recently the calculation of holographic free energy for mass-deformed ABJM model (mABJM) with supersymmetry and global symmetry was tackled by Bobev…
Perturbative solutions of holography on
Nakwoo Kim, Se-Jin Kim
We apply the recently proposed perturbative technique to solve the supergravity BPS equations of theories put on . In particular, we have calculated the coeffic…
"Invisible" axion rolling through the QCD phase transition
Jihn E. Kim, Se-Jin Kim
The origin of `invisible' axion in four dimensional effective beyond-standard models from string compactification is discussed and its refined passover through the QCD phase transi…
Flavor mixing inspired by flipped SU(5) GUT
Junu Jeong, Jihn E. Kim, Se-Jin Kim
We obtain a phenomenologically acceptable Cabibbo-Kobayashi-Maskawa matrix in a flipped SU(5) model inspired by the compactification of heterotic string .
Axion energy density, bottle neck period, and ratios between early and late times
Jihn E. Kim, Se-Jin Kim, Soonkeon Nam
The possibility of the "invisible" axion being cold dark matter relies on the acceptable estimates of the current axion energy density. The estimate depends on the nature of QCD ph…
"Invisible" QCD axion rolling through the QCD phase transition
Jihn E. Kim, Se-Jin Kim
Visible matter in the current Universe is a consequence of the phase transition of the strong force, quantum chromodynamics (QCD). This phase transition has occurred at the Univers…
Crossed products of operator systems
Samuel J. Harris, Se-Jin Kim
In this paper we introduce the crossed product construction for a discrete group action on an operator system. In analogy to the work of E. Katsoulis and C. Ramsey, we describe thr…
Chromatic numbers and a Lovász type inequality for non-commutative graphs
Se-Jin Kim, Arthur Mehta
Non-commutative graph theory is an operator space generalization of graph theory. Well known graph parameters such as the independence number and Lovász theta function were first g…
A synchronous game for binary constraint systems
Se-Jin Kim, Vern I. Paulsen, Christopher Schafhauser
Recently, W. Slofstra proved that the set of quantum correlations is not closed. We prove that the set of synchronous quantum correlations is not closed, which implies his result,…
