The interplay between a multitude of electronic, spin, and lattice degrees freedom underlies the complex phase diagrams quantum materials. Layer stacking in van der Waals (vdW) heterostructures is responsible for exotic electronic magnetic properties, which inspires control two-dimensional magnetism. Beyond order interlayer magnetism, we discover spin-shear coupling mechanism subtle shear atomic layers can have profound effect on intralayer family vdW antiferromagnets. Using time-resolved...
Abstract In type-II Weyl semimetals (WSMs), the tilting of cones leads to coexistence electron and hole pockets that touch at nodes. These electrons holes experience Berry curvature generated by nodes, leading an anomalous Hall effect is highly sensitive Fermi level position. Here we have identified field-induced ferromagnetic MnBi 2-x Sb x Te 4 as ideal WSM with a single pair By employing combination quantum oscillations high-field measurements, resolved evolution Fermi-surface sections...
Defects in hexagonal boron nitride (hBN), a two-dimensional van der Waals material, have attracted great deal of interest because its potential various quantum applications. Due to hBN's nature, the spin center hBN can be engineered proximity target providing advantages over three-dimensional counterparts, such as nitrogen-vacancy diamond. Here we propose novel sensing protocol driven by exchange interaction between and underlying magnetic substrate induced effect. By first-principles...

According principle system, proposed theory is systematically described. aim map given results in form vector into time sequence. Subsequently, we develop platform whose core components are an arbitrary waveform generator and tunable laser, thus it can generate set six signals exact sequential relationship....
Defects in hexagonal boron nitride (hBN), a two-dimensional van der Waals material, have raised wide range interest for its potential various quantum applications. Due to hBN's 2D nature, spin center hBN can be engineered close proximity target providing advantages over their 3D counterparts, such as nitrogen-vacancy (NV) diamond. Here we propose novel sensing protocol driven by exchange interaction between and the underlying magnetic substrate induced effect. By first-principle calculation,...
We present a comprehensive numerical study on the kinetics of phase transition that is characterized by two nonconserved scalar order parameters coupled special linear-quadratic interaction. This particular Ginzburg-Landau theory has been proposed to describe charge and magnetic in nickelates collinear stripe cuprates. The inhomogeneous state such systems at low temperatures consists domains separated quasimetallic domain walls where reduced. By performing large-scale cell dynamics...
Weyl semimetals (WSMs) are three-dimensional topological materials that exhibit fascinating properties due to the presence of nodes in their band structure. However, existing WSMs discovered so far often possess multiple pairs nodes, posing a challenge disentangling contributions transport phenomena from different energy bands. To overcome this challenge, we have identified field-induced ferromagnetic MnBi$_{2-x}$Sb$_{x}$Te$_{4}$ as an ideal type-II WSM with single pair nodes. By employing...
