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…
Orbital Magnetization of Correlated States in Twisted Bilayer Transition Metal Dichalcogenides
Xiaoyu Liu, Chong Wang, Haoran Chen +3
Recent observations of quantum anomalous Hall effects in moiré systems have revealed the emergence of interaction-driven ferromagnetism with significant orbital contributions. To c…
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…
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…
Strain-driven stabilization of a room-temperature chiral multiferroic with coupled ferroaxial and ferroelectric order
Guodong Ren, Gwan Yeong Jung, Huandong Chen +9
Noncollinear ferroic materials are sought after as testbeds to explore the intimate connections between topology and symmetry, which result in electronic, optical and magnetic func…
Ferromagnetism and Topology of the Higher Flat Band in a Fractional Chern Insulator
Heonjoon Park, Jiaqi Cai, Eric Anderson +18
The recent observation of the fractional quantum anomalous Hall effect in moiré fractional Chern insulators provides an opportunity to investigate zero magnetic field anyons. To po…
Higher Landau-Level Analogs and Signatures of Non-Abelian States in Twisted Bilayer MoTe
Chong Wang, Xiao-Wei Zhang, Xiaoyu Liu +3
Recent experimental discovery of fractional Chern insulators at zero magnetic field in moiré superlattices has sparked intense interests in bringing Landau level physics to flat Ch…
Polarization-driven band topology evolution in twisted MoTe and WSe
Xiao-Wei Zhang, Chong Wang, Xiaoyu Liu +3
Motivated by recent experimental observations of opposite Chern numbers in -type twisted MoTe and WSe homobilayers, we perform large-scale density-functional-theory (DFT…
Dynamical criticality of spin-shear coupling in van der Waals antiferromagnets
Faran Zhou, Kyle Hwangbo, Qi Zhang +15
The interplay between a multitude of electronic, spin, and lattice degrees of freedom underlies the complex phase diagrams of quantum materials. Layer stacking in van der Waals (vd…
Chiral anomaly in Weyl semimetals from spin current injection
Yang Gao
Weyl semimetals are well-known for hosting topologically protected linear band crossings, serving as the analog of the relativistic Weyl Fermions in the condensed matter context. S…
