DOI: 10.1002/andp.202300072
Abstract: Topological superconductors are foreseen as good candidates for the search of Majorana zero modes, where they appear as edge states and can be used for quantum computation. In this context, it becomes necessary to study… read more here.

DOI: 10.1103/physrevb.101.235308
Abstract: We investigate transport through a normal-superconductor (NS) junction made from a quantum spin Hall (QSH) system with helical edge states and a two-dimensional (2D) chiral topological superconductor (TSC) having a chiral Majorana edge mode. We… read more here.

DOI: 10.1103/physrevb.97.205134
Abstract: Starting from a minimal model of a time-reversal-invariant topological superconductor in two dimensions, the author shows that an in-plane magnetic field could drive the superconductor into a second-order topological phase, which features Majorana zero modes,… read more here.

DOI: 10.1103/physrevb.98.161107
Abstract: We use magnetization measurements, high-resolution angle-resolved photoemission spectroscopy (ARPES), and density functional theory (DFT) calculations to study the electronic properties of Au${}_{2}$Pb, a topological superconductor candidate. The magnetization measurements reveal three discontinuities at 40, 51,… read more here.

DOI: 10.1103/physrevlett.120.066801
Abstract: We introduce a model of interacting Majorana fermions that describes a superconducting phase with a topological order characterized by the Fibonacci topological field theory. Our theory, which is based on a SO(7)_{1}/(G_{2})_{1} coset factorization, leads… read more here.

DOI: 10.1103/physrevlett.127.217002
Abstract: We investigated the superconducting properties of the topological superconductor α-PdBi_{2} at ambient and external pressures up to 1.77 GPa using muon spin rotation experiments. The ambient pressure measurements evince a fully gapped s-wave superconducting state in… read more here.
