Strain-Gradient Engineering of Topological, Nonlinear Optical, and Spin Chiral Responses in MnBi2Te4

Strain gradients arising from nonuniform interlayer expansion in layered van der Waals materials simultaneously modulate interlayer coupling and break inversion symmetry, yet their potential as a control knob for topological quantum materials remains unexplored. Using first-principles calculations, we demonstrate tha...
