Mask2Hand: Learning to Predict the 3D Hand Pose and Shape from Shadow
Li-Jen Chang, Yu-Cheng Liao, Chia-Hui Lin +1
We present a self-trainable method, Mask2Hand, which learns to solve the challenging task of predicting 3D hand pose and shape from a 2D binary mask of hand silhouette/shadow witho…
Create Dirac Cones in Your Favorite Materials
Chia-Hui Lin, Wei Ku
Realization of conically linear dispersion, termed as Dirac cones, has recently opened up exciting opportunities for high-performance devices that make use of the peculiar transpor…
First-Principle Wannier function analysis of the electronic structure of PdTe: Weaker magnetism and superconductivity
Chinedu E. Ekuma, Chia-Hui Lin, Juana Moreno +2
We report a first-principles Wannier function study of the electronic structure of PdTe. Its electronic structure is found to be a broad three-dimensional Fermi surface with highly…
Impact of the 2 Fe unit cell on the electronic structure measured by ARPES in iron pnictides
V. Brouet, M. Fuglsang Jensen, Ping-Hui Lin +7
In all iron pnictides, the positions of the ligand alternatively above and below the Fe plane create 2 inequivalent Fe sites. This results in 10 Fe 3d bands in the electronic struc…
One-Fe versus Two-Fe Brillouin Zone of Fe-Based Superconductors: Creation of the Electron Pockets via Translational Symmetry Breaking
Chia-Hui Lin, Tom Berlijn, Limin Wang +3
We investigate the physical effects of translational symmetry breaking in Fe-based high-temperature superconductors due to alternating anion positions. In the representative parent…
Do Transition Metal Substitutions Dope Carriers in Iron Based Superconductors?
Tom Berlijn, Chia-Hui Lin, William Garber +1
We investigate the currently debated issue concerning whether transition metal substitutions dope carriers in iron based superconductors. From first-principles calculations of the…
Novel Insulating Magnetism in Vacancy-Ordered K2Fe4Se5
Wei-Guo Yin, Chia-Hui Lin, Wei Ku
We unveil the novel physical origin of the insulating block checkerboard antiferromagnetism in vacancy-ordered K2Fe4Se5. Our first-principles electronic structure analysis reveals…
Pure spin current generation in a Rashba-Dresselhaus quantum channel
Chia-Hui Lin, Chi-Shung Tang, Yia-Chung Chang
We demonstrate a spin pump to generate pure spin current of tunable intensity and polarization in the absence of charge current. The pumping functionality is achieved by means of a…
Effects of disordered Ru substitution in BaFeAs: Realization of superdiffusion mechanism in real materials
Limin Wang, Tom Berlijn, Yan Wang +3
An unexpected insensitivity of the Fermi surface to impurity scattering is found in Ru substituted BaFeAs from first-principles theory, offering a natural explanation of th…
Orbital-Parity Distinct Superconducting Pairing Structures of Fe-based Superconductors under Glide Symmetry
Chia-Hui Lin, Chung-Pin Chou, Wei-Guo Yin +1
We investigate an unusual symmetry of Fe-based superconductors (FeSCs) and find novel superconducting pairing structures. FeSCs have a minimal translational unit cell composed of t…
Lifshitz Transition and Superconductivity Enhancement in High Pressure 16 Li
Chia-Hui Lin, Tom Berlijn, Wei Ku
The Fermi surface topology of 16 Li at high pressures is studied using a recently developed first-principles unfolding method. We find the occurrence of a Lifshitz transition a…
