Author(s): Jaden Thomas-Markarian, Kartiek Agarwal, and Ivar Martin Topological superconductors are believed to host exotic quasiparticle excitations known as Majorana zero modes (MZMs), with much of the evidence based on BCS mean-field theory. The direct application of mean-field arguments is tenuous in finite, isolated systems relevant in some experiments. Here, w… [Phys. Rev. Lett. 137, 086504] Published Tue Aug 18, 2026
