The spatial texture of internal degree of freedom of electrons has profoundeffects on the properties of materials. Such texture in real space can manifestas an emergent magnetic field (or Berry curvature), which is expected to induceinteresting valley/spin-related transport phenomena. Moir\'e pattern, whichemerges as a spatial variation at the interface of 2D atomic crystals, providesa natural platform for investigating such real space Berry curvature effects.Here we study moir\'e structures formed in homobilayer transition metaldichalcogenides (TMDs) due to twisting, various uniform strain profiles, andtheir combinations, where electrons can reside in either layer with the layerindex serving as an internal degree of freedom. The layer pseudo-spin exhibitsvortex/antivortex textures in the moir\'e supercell, leading to a giantgeometric magnetic field and a scalar potential. Within a geometric picture,the moir\'e magnetic field is found as the cross product of the gradients ofthe out-of-plane pseudo-spin and the in-plane pseudo-spin orientationrespectively. We discover dual roles of uniform strain: Besides being a causeof the moire atomic texture in the homobilayer, it also contributes apseudo-gauge potential that modifies the local phase of interlayer coupling.Consequently, strain can be employed to tune the in-plane pseudo-spin texture,while interlayer bias tunes the out-of-plane pseudo-spin, and we show how themoir\'e magnetic field's spatial profile, intensity, and flux per supercell canbe engineered. Through the geometric scalar correction, the landscape of thescalar potential can also be engineered along with the moir\'e magnetic field,forming distinct effective lattice structures. These properties render TMDmoir\'e structures promising to build tunable flux lattices for transport andtopological material applications.
