Algebraic Properties of Riemannian Manifolds
Youngjoo Chung, Chi-Ok Hwang, Hyun Seok Yang
Algebraic properties are explored for the curvature tensors of Riemannian manifolds, using the irreducible decomposition of curvature tensors. Our method provides a powerful tool t…
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…
Yang-Lee Zeros of the Triangular Ising Antiferromagnets
Chi-Ok Hwang, Seung-Yeon Kim
Using both the exact enumeration method (microcanonical transfer matrix) for a small system (L = 9) and the Wang-Landau Monte Carlo algorithm for large systems to L = 30, we obtain…
On the Rapid Estimation of Permeability for Porous Media Using Brownian Motion Paths
Chi-Ok Hwang, James A. Given, Michael Mascagni
We describe two efficient methods of estimating the fluid permeability of standard models of porous media by using the statistics of continuous Brownian motion paths that initiate…
An Efficient Modified "Walk On Spheres" Algorithm for the Linearized Poisson-Boltzmann Equation
Chi-Ok Hwang, Michael Mascagni
A discrete random walk method on grids was proposed and used to solve the linearized Poisson-Boltzmann equation (LPBE) \cite{Rammile}. Here, we present a new and efficient grid-fre…
