Assuming a single real scalar field with a sine-Gordon self-interaction, the generalized quadratic nonmetricity invariant Q controls the brane width while keeping the shape of the energy density. By considering power corrections of the invariant Q in the gravitational Lagrangian, the sine-Gordon potential is modified exhibiting new barriers and false vacuum. As a result, the domain wall brane obtains an inner structure, and it undergoes a splitting process. In addition, we also propose a nonminimal coupling between a bulk fermion field and the nonmetricity invariant Q. Such geometric coupling leads to a massless chiral fermion bound to the 3-brane and a stable tower of nonlocalized massive states.", optnote="WOS:000880673200004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5410), last updated on Fri, 25 Nov 2022 08:32:27 +0000", issn="2470-0010", doi="10.1103/PhysRevD.106.024033", opturl="https://arxiv.org/abs/2203.05720", opturl="https://doi.org/10.1103/PhysRevD.106.024033", language="English" }
