Distilling universal machine-learning potentials for moiré lattices across one million atoms
Thomas Huang, Yueyao Fan, Kaichen Xie +7
Atomic reconstruction reshapes moiré materials across multiple scales, from local structure and polarization textures to global electronic topology, yet direct \textit{ab initio} m…
Switching Chern number by sliding and gating in alternately twisted tetralayer MoTe2
Xiao-Wei Zhang, Kaijie Yang, Xiaodong Xu +2
Switching the bulk Chern number in topological materials is of central importance for the design of topological electronic devices. Motivated by recent observations of integer and…
Ward identities and orbital magnetization in current density functional theory
Giovanni Vignale, Junren Shi, Di Xiao +1
We revisit the derivation of the orbital magnetization formula for periodic crystals in current density functional theory (CDFT)[1]. Our new derivation computes the linear response…
Layerwise Stratification and Band Reordering in Twisted Multilayer MoTe
Yueyao Fan, Xiao-Wei Zhang, Yusen Ye +5
We introduce a generalizable, physics informed strategy for generating training data that enables a machine learning force field accurate over a broad range of twist angles and sta…
Twist-angle transferable continuum model and second flat Chern band in twisted MoTe2 and WSe2
Xiao-Wei Zhang, Kaijie Yang, Chong Wang +3
We develop a twist-angle transferable continuum model for twisted transition metal dichalcogenide (tTMD) homobilayers, using tMoTe2 and tWSe2 as examples. All model parameters are…
Geometric Origin of Phonon Magnetic Moment in Dirac Materials
Wenqin Chen, Xiao-Wei Zhang, Ting Cao +2
We develop a theory for the phonon magnetic moment in doped Dirac materials, treating phonons as emergent gauge and gravitational fields coupled to Dirac fermions in curved space.…
Adiabatic Pumping of Orbital Magnetization by Spin Precession
Yafei Ren, Wenqin Chen, Chong Wang +2
We propose adiabatic pumping of orbital magnetization driven by coherent spin precession, facilitating the rectification of this precession. The orbital magnetization originates fr…
Gauge theory of giant phonon magnetic moment in doped Dirac semimetals
Wenqin Chen, Xiao-Wei Zhang, Ying Su +3
We present a quantum theory of phonon magnetic moment in doped Dirac semimetals. Our theory is based on an emergent gauge field approach to the electron-phonon coupling, applicable…
