First- and Second-Order Topological Superconductivity and Temperature-Driven Topological Phase Transitions in the Extended Hubbard Model with Spin-Orbit Coupling.
TL;DR: This Letter investigates the superconducting pairing instability of the two-dimensional extended Hubbard model with both Rashba and Dresselhaus spin-orbit coupling within the mean-field level at both zero and finite temperature and suggests new possibilities in interacting spin- orbit coupled systems by unifying both first- and higher-order topological superconductors in a simple but realistic microscopic model.
Journal ArticleDOI
Vortex-line topology in iron-based superconductors with and without second-order topology
TL;DR: In this paper, the authors investigated the interplay between the second-order topology and the vortex lines in both weak and strong-Zeeman-field regimes, and found that vortex lines far away from the hinges are topologically nontrivial in the weakly doped regime, regardless of whether the second order topology is present or not.
Journal ArticleDOI
Majorana corner flat bands in two-dimensional second-order topological superconductors
TL;DR: In this paper, it was shown that confining a second-order topological superconductor with a harmonic potential leads to a proliferation of Majorana corner modes, which have a fundamentally different origin from that of the conventional mechanism.
Sublattice-enriched tunability of bound states in second-order topological insulators and superconductors
TL;DR: In this paper , the Kane-Mele model with honeycomb-lattice structure was used to illustrate the underlying physics and the existence of sublattices degrees of freedom can enrich the tunability of bound states on the boundary and hence lift the constraint on their locations.
Corner- and sublattice-sensitive Majorana zero modes on the kagome lattice
TL;DR: In this article , the impact of sublattice terminations on the boundary physics on the two-dimensional kagome lattice was studied and it was shown that the energies of the Dirac points of helical edge states sensitively depend on the terminating sublATTices at the edge.
