This theoretical condensed-matter study examines how an electric field affects the electronic spectrum and localization in quasiperiodic chains modeled with Harper and Fibonacci potentials. It reports localized ladder spectra under strong fields and smoothing with linearly decreasing gaps under weak fields. When…

This theoretical paper analyzes vortex solutions in two-component superconductors within a U(1) x U(1) Ginzburg-Landau framework. It reports that exponentially screened magnetic fields are only found in special cases, while most parameter choices yield delocalized magnetic fields with slowly decaying tails. It also…
