DPmoire: A tool for constructing accurate machine learning force fields in moiré systems
Jiaxuan Liu, Zhong Fang, Hongming Weng +1
In moiré systems, the impact of lattice relaxation on electronic band structures is significant, yet the computational demands of first-principles relaxation are prohibitively high…
Universal Moiré-Model-Building Method without Fitting: Application to Twisted MoTe and WSe
Yan Zhang, Hanqi Pi, Jiaxuan Liu +8
We develop a comprehensive method to construct analytical continuum models for moiré systems directly from first-principle calculations without any parameter fitting. The core idea…
The inadequacy of the -T curve for phase transitions in the presence of magnetic fields
Shengnan Zhang, Zhong Fang, Hongming Weng +1
The curve is traditionally employed to discern metallic, semiconductor, and insulating behaviors in materials, with any deviations often interpreted as indicative of phase t…
Majorana zero modes under electron correlation
Ziyue Qi, Hongming Weng, Kun Jiang
In this work, we perform a systematic investigation of the correlated topological superconductors (TSCs), especially their non-trivial Majorana zero modes (MZMs). Compared to the n…
Observation of dichotomic field-tunable electronic structure in twisted monolayer-bilayer graphene
Hongyun Zhang, Qian Li, Youngju Park +18
Twisted bilayer graphene (tBLG) provides a fascinating platform for engineering flat bands and inducing correlated phenomena. By designing the stacking architecture of graphene lay…
First-principles methodology for studying magnetotransport in narrow-gap semiconductors: an application to Zirconium Pentatelluride ZrTe5
Hanqi Pi, Shengnan Zhang, Yang Xu +3
The origin of anomalous resistivity peak and accompanied sign reversal of Hall resistivity of ZrTe has been under debate for a long time. Although various theoretical models ha…
Complex field-, temperature-, and angle-dependent Hall effects from intrinsic Fermi surface revealed by first-principles calculations
ShengNan Zhang, Zhihao Liu, Hanqi Pi +3
The Hall effect, ever intriguing since its discovery, has spurred the exploration of its phenomena, intensified by advances in topology and novel materials. Differentiating the ord…
A combined First-principles and Boltzmann transport theory methodology for studying magnetotransport in magnetic materials
Zhihao Liu, Shengnan Zhang, Zhong Fang +2
Unusual magnetotransport behaviors, such as temperature-dependent negative magnetoresistance (MR) and bowtie-shaped MR, have puzzled us for a long time. Although several mechanisms…
