MoireKP: An Automated Workflow for Symmetry-Constrained Moiré Continuum Models
Yan Zhang, Hanqi Pi, Wangqian Miao +5
First-principles Hamiltonians contain the electronic information needed to study moiré materials, but their size makes subsequent calculations costly. We present MoireKP, an automa…
Pairing from repulsive interactions in twisted WSe2 from functional renormalization
Hannes Braun, Dumitru Călugăru, Pietro M. Bonetti +9
Motivated by the observation of superconductivity in twisted bilayer WSe over an extended range of displacement fields, reaching from the correlated insulator down to zero fiel…
A Catalogue of Topological Moiré Bands in Twisted Semiconductors
Jiaheng Li, Yan Zhang, Jiaxuan Liu +5
Twisted two-dimensional semiconductors provide a route to flat and topological moiré minibands, but systematic principles for organizing their material dependence have remained unc…
A Geometric Design Principle for Topological Phases in Twisted Triangular-Lattice Bilayers
Jiaheng Li, Jiaxuan Liu, Yan Zhang +3
Twisted van der Waals bilayers provide a versatile platform for moiré electronic states, yet a transferable symmetry-based principle for time-reversal-invariant moir…
Andreev Reflection to Probe Momentum-Dependent Spin Polarization in Altermagnet CrSb
Yan Zhang, Yixuan Luo, Yue Yang +7
Altermagnetic materials have recently emerged as promising candidates for next-generation spintronic applications, characterized by the k-dependent spin-splitted band structure and…
Coexistence of topologically nontrivial and trivial insulating states in topological Anderson Chern insulator
Bo Yin, Yan Zhang, Anqi Wang +3
The interplay between disorder and topology has become a central theme in condensed matter physics. Disorder can not only destroy topological phases but also induce them, as exempl…
Chern-Selective multi-valley Flat Bands in Twisted Mono-Bilayer and Mono-Trilayer MoTe
Ziyue Qi, Hanqi Pi, Yan Zhang +6
The interplay between moiré flat bands originating from different valleys can give rise to a variety of exotic quantum phases. In this work, we investigate the electronic propertie…
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…
