Origin of doping-induced suppression and reemergence of magnetism in LaFeAsOH
Chang-Youn Moon, Hyowon Park, Kristjan Haule +1
We investigate the evolution of magnetic properties as a function of hydrogen doping in iron based superconductor LaFeAsOH using the dynamical mean-field theory combine…
Observation of Ultralong Valley Lifetime in WSe2/MoS2 Heterostructures
Jonghwan Kim, Chenhao Jin, Bin Chen +9
The valley degree of freedom in two-dimensional (2D) crystals recently emerged as a novel information carrier in addition to spin and charge. The intrinsic valley lifetime in 2D tr…
Generation of a non-zero discord bipartite state with classical second-order interference
Yujun Choi, Kang-Hee Hong, Hyang-Tag Lim +7
We report investigation on quantum discord in classical second-order interference. In particular, we theoretically show that a bipartite state with D = 0.311 of discord can be gene…
Text-guided Attention Model for Image Captioning
Jonghwan Mun, Minsu Cho, Bohyung Han
Visual attention plays an important role to understand images and demonstrates its effectiveness in generating natural language descriptions of images. On the other hand, recent st…
Broken-Symmetry Quantum Hall States in Twisted Bilayer Graphene
Youngwook Kim, Jaesung Park, Intek Song +8
Twisted bilayer graphene offers a unique bilayer two-dimensional-electron system where the layer separation is only in sub-nanometer scale. Unlike Bernal-stacked bilayer, the layer…
Experimental Realization of Type-II Dirac Fermions in PdTe Superconductor
Han-Jin Noh, Jinwon Jeong, En-Jin Cho +3
A Dirac fermion in a topological Dirac semimetal is a quadruple-degenerate quasi-particle state with a relativistic linear dispersion. Breaking either time-reversal or inversion sy…
Large-Scale Image Retrieval with Attentive Deep Local Features
Hyeonwoo Noh, Andre Araujo, Jack Sim +2
We propose an attentive local feature descriptor suitable for large-scale image retrieval, referred to as DELF (DEep Local Feature). The new feature is based on convolutional neura…
Examining the origin of dark matter mass at colliders
Minho Kim, Hye-Sung Lee, Myeonghun Park +1
As conventional dark matter scenarios have been probed extensively so far, the physics of a light dark matter charged under a new gauge group (dark gauge group) becomes one of new…
Unknotted gropes, Whitney towers, and doubly slicing knots
Jae Choon Cha, Taehee Kim
We study the structure of the exteriors of gropes and Whitney towers in dimension 4, focusing on their fundamental groups. In particular we introduce a notion of unknottedness of g…
MarioQA: Answering Questions by Watching Gameplay Videos
Jonghwan Mun, Paul Hongsuck Seo, Ilchae Jung +1
We present a framework to analyze various aspects of models for video question answering (VideoQA) using customizable synthetic datasets, which are constructed automatically from g…
Long-range interactions in the effective low energy Hamiltonian of Sr2IrO4: a core level resonant inelastic x-ray scattering study
S. Agrestini, C. -Y. Kuo, M. Moretti Sala +12
We have investigated the electronic structure of Sr2IrO4 using core level resonant inelastic x-ray scattering. The experimental spectra can be well reproduced using ab initio densi…
Direct observation of the M2 phase with its Mott transition in a VO film
Hoon Kim, Tetiana V. Slusar, Dirk Wulferding +7
In VO, the explicit origin of the insulator-to-metal transition is still disputable between Peierls and Mott insulators. Along with the controversy, its second monoclinic (M2)…
Surface orbitronics: new twists from orbital Rashba physics
Dongwook Go, Jan-Philipp Hanke, Patrick M. Buhl +5
When the inversion symmetry is broken at a surface, spin-orbit interaction gives rise to spin-dependent energy shifts - a phenomenon which is known as the spin Rashba effect. Recen…
Anomalous Hall effects beyond Berry magnetic fields in a Weyl metal phase
Iksu Jang, Jaeho Han, Ki-Seok Kim
Applying time-varying magnetic fields to Weyl metals, a pair of Weyl points become oscillating. This oscillating monopole and anti-monopole pair gives rise to AC Berry magnetic fie…
Asymptotic boundary behavior of the Bergman curvatures of a pseudoconvex domain
Sungmin Yoo
We present a method of obtaining a lower bound estimate of the curvatures of the Bergman metric without using the regularity of the kernel function on the boundary. As an applicati…
Curvaton as dark matter with secondary inflation
Jinn-Ouk Gong, Naoya Kitajima, Takahiro Terada
We consider a novel cosmological scenario in which a curvaton is long-lived and plays the role of cold dark matter (CDM) in the presence of a short, secondary inflation. Non-trivia…
Convergence Analysis of MAP based Blur Kernel Estimation
Sunghyun Cho, Seungyong Lee
One popular approach for blind deconvolution is to formulate a maximum a posteriori (MAP) problem with sparsity priors on the gradients of the latent image, and then alternatingly…
Stylized facts in social networks: Community-based static modeling
Hang-Hyun Jo, Yohsuke Murase, János Török +2
The past analyses of datasets of social networks have enabled us to make empirical findings of a number of aspects of human society, which are commonly featured as stylized facts o…
A map of the non-thermal WIMP
Hyungjin Kim, Jeong-Pyong Hong, Chang Sub Shin
We study the effect of the elastic scattering on the non-thermal WIMP, which is produced by direct decay of heavy particles at the end of reheating. The non-thermal WIMP becomes im…
