Tricriticality and finite-size scaling in the triangular Blume-Capel ferromagnet

Autor: Mataragkas, Dimitrios, Vasilopoulos, Alexandros, Fytas, Nikolaos G., Kim, Dong-Hee

We report on numerical simulations of the two-dimensional spin-$1$ Blume-Capel ferromagnet embedded in a triangular lattice. Utilizing a range of Monte Carlo and finite-size scaling techniques, we explore several critical aspects along the crystal fi

Joint-Embedding Predictive Architecture for Self-Supervised Learning of Mask Classification Architecture

Autor: Kim, Dong-Hee, Cho, Sungduk, Cho, Hyeonwoo, Park, Chanmin, Kim, Jinyoung, Kim, Won Hwa

In this work, we introduce Mask-JEPA, a self-supervised learning framework tailored for mask classification architectures (MCA), to overcome the traditional constraints associated with training segmentation models. Mask-JEPA combines a Joint Embeddin

CNG-SFDA:Clean-and-Noisy Region Guided Online-Offline Source-Free Domain Adaptation

Autor: Cho, Hyeonwoo, Park, Chanmin, Kim, Dong-Hee, Kim, Jinyoung, Kim, Won Hwa

Domain shift occurs when training (source) and test (target) data diverge in their distribution. Source-Free Domain Adaptation (SFDA) addresses this domain shift problem, aiming to adopt a trained model on the source domain to the target domain in a

Neural-network quantum state study of the long-range antiferromagnetic Ising chain

Autor: Kim, Jicheol, Kim, Dongkyu, Kim, Dong-Hee

Publikováno v: Phys. Rev. E 109, 064123 (2024)

We investigate quantum phase transitions in the transverse field Ising chain with algebraically decaying long-range (LR) antiferromagnetic interactions using the variational Monte Carlo method with the restricted Boltzmann machine employed as a trial

Slowest and Fastest Information Scrambling in the Strongly Disordered XXZ Model

Autor: Kim, Myeonghyeon, Kim, Dong-Hee

Publikováno v: Phys. Rev. B 107, L220203 (2023)

We present a perturbation method to compute the out-of-time-ordered correlator in the strongly disordered Heisenberg XXZ model in the deep many-body localized regime. We characterize the discrete structure of the information propagation across the ei

Effect of Egg White Combined with Chalcanthite on Lipopolysaccharide induced Inflammatory Cytokine Expression in RAW 264.7 cells

Autor: Choi Eun-A, Yoon Jeung-Won, Choi Hak-Joo, Kim Dong-Hee, Yoo Hwa-Seung

Publikováno v: Journal of Pharmacopuncture, Vol 15, Iss 1, Pp 7-11 (2012)

Historically, mineral compound herbal medicines have long been used in treatments of immune-related diseases in Korea, China and other Asian countries. In this study, we inv-estigated the anti-inflammatory effect of egg white combined with chalcanthi

Tensor network calculation of the logarithmic correction exponent in the XY model

Autor: Hong, Seongpyo, Kim, Dong-Hee

Publikováno v: J. Phys. Soc. Jpn. 91, 084003 (2022)

We study the logarithmic correction to the scaling of the first Lee-Yang (LY) zero in the classical $XY$ model on square lattices by using tensor renormalization group methods. In comparing the higher-order tensor renormalization group (HOTRG) and th
