Fidelity susceptibility and geometric response in flux-tuned Dirac systems: exact results from a low-energy two-level reduction

C. A. S. Almeida

We study the parametric sensitivity of two-dimensional massive Dirac fermions subject to Aharonov-Bohm flux insertion, using the Bures metric (fidelity susceptibility) as the centr…

Gravitationally induced wave-function collapse from dynamical bifurcation

C. A. S. Almeida

We propose an effective non-relativistic framework in which wave-function collapse emerges as a deterministic dynamical instability induced by gravitational self-interaction and re…

Chiral Fermion Localization in Two-Kink Scalar Backgrounds: Tunable Brane Positioning and Universal Divergence at the Single-Kink Limit

H. P. Pinheiro, C. A. S. Almeida

The localization of chiral fermionic zero modes in scalar field backgrounds with domain wall structure is a central mechanism in brane-world scenarios. We investigate this mechanis…
