  The present work explores the potential for observing multiple reentrant
localization behavior in a double-stranded helical (DSH) system, extending
beyond the conventional nearest-neighbor hopping interaction. The DSH system is
considered to have hopping dimerization in each strand, while also being
subjected to a transverse electric field. The inclusion of an electric field
serves the dual purpose of inducing quasiperiodic disorder and strand-wise
staggered site energies. Two reentrant localization regions are identified: one
exhibiting true extended behavior in the thermodynamic limit, while the second
region shows quasi-extended characteristics with partial spreading within the
helix. The DSH system exhibits three distinct single-particle mobility edges
linked to localization transitions present in the system. The analysis in this
study involves examining various parameters such as the single-particle energy
spectrum, inverse participation ratio, local probability amplitude, and more.
Our proposal, combining achievable hopping dimerization and induced correlated
disorder, presents a unique opportunity to study phenomenon of reentrant
localization, generating significant research interest.
