First-Principles Approach to Spin Excitations in Noncollinear Magnetic Systems
Hsiao-Yi Chen, Ryotaro Arita, Yusuke Nomura
We present a first-principles method based on density functional theory and many-body perturbation theory for computing spin excitations in magnetic systems with noncollinear spin…
Giant Hall effect in a highly conductive frustrated magnet GdCu
Kosuke Karube, Yoshichika Ōnuki, Taro Nakajima +10
The Hall effect is one of the most fundamental but elusive phenomena in condensed matter physics due to the rich variety of underlying mechanisms. Here we report an exceptionally l…
Topological Hall effect of Skyrmions from First Principles
Hsiao-Yi Chen, Takuya Nomoto, Max Hirschberger +1
We formulate a first-principles approach for calculating the topological Hall effect (THE) in magnets with noncollinear nanoscale spin textures. We employ a modeling method to dete…
Heterotic Surface Defects and Dualities from 2d/4d Indices
Heng-Yu Chen, Hsiao-Yi Chen
Starting with the superconformal indices for 4d N=2 and N=1 supersymmetric gauge theories, which are related by superpotential deformation, we perform the contour integrations and…
Connecting Mirror Symmetry in 3d and 2d via Localization
Heng-Yu Chen, Hsiao-Yi Chen, Jun-Kai Ho
We explicitly apply localization results to study the interpolation between three and two dimensional mirror symmetry for Abelian gauge theories with four supercharges. We first us…
