Higher-order topological superconductivity of spin-polarized fermions

J Ahn, BJ Yang - Physical Review Research, 2020 - APS
We study the superconductivity of spin-polarized electrons in centrosymmetric ferromagnetic
metals. Due to the spin polarization and the Fermi statistics of electrons, the …

Topological superconductivity in two-dimensional altermagnetic metals

D Zhu, ZY Zhuang, Z Wu, Z Yan - Physical Review B, 2023 - APS
Bringing magnetic metals into superconducting states represents an important approach for
realizing unconventional superconductors and potentially even topological …

Weak-pairing higher order topological superconductors

Y Wang, M Lin, TL Hughes - Physical Review B, 2018 - APS
Conventional topological superconductors are fully gapped in the bulk but host gapless
Majorana modes on their boundaries. We instead focus on a new class of superconductors …

Majorana corner modes and tunable patterns in an altermagnet heterostructure

YX Li, CC Liu - Physical Review B, 2023 - APS
The mutual competition and synergy of magnetism and superconductivity provide us with a
very valuable opportunity to access topological superconductivity and Majorana fermions …

Topological superconducting phase and Majorana fermions in half-metal/superconductor heterostructures

SB Chung, HJ Zhang, XL Qi, SC Zhang - Physical Review B—Condensed …, 2011 - APS
As a half-metal is spin polarized at its Fermi level by definition, it was conventionally thought
to have little proximity effect to an s-wave superconductor. Here we show that with interface …

Chiral topological superconductivity arising from the interplay of geometric phase and electron correlation

W Qin, L Li, Z Zhang - Nature Physics, 2019 - nature.com
In modern theory of solids, many-electron correlations can give rise to superconductivity,
while the Berry or geometric phase is responsible for non-trivial topology. So far, these two …

Tunable Majorana corner states in a two-dimensional second-order topological superconductor induced by magnetic fields

X Zhu - Physical Review B, 2018 - APS
A two-dimensional second-order topological superconductor exhibits a finite gap in both
bulk and edges, with the nontrivial topology manifesting itself through Majorana zero modes …

Second-order bulk-boundary correspondence in rotationally symmetric topological superconductors from stacked Dirac Hamiltonians

E Roberts, J Behrends, B Béri - Physical Review B, 2020 - APS
Two-dimensional second-order topological superconductors host zero-dimensional
Majorana bound states at their boundaries. In this work, focusing on rotation-invariant …

High-throughput investigations of topological and nodal superconductors

F Tang, S Ono, X Wan, H Watanabe - Physical Review Letters, 2022 - APS
The theory of symmetry indicators has enabled database searches for topological materials

Majorana flat bands, chiral Majorana edge states, and unidirectional Majorana edge states in noncentrosymmetric superconductors

A Daido, Y Yanase - Physical Review B, 2017 - APS
We study two-dimensional noncentrosymmetric nodal superconductors under Zeeman field
and clarify the field-angle dependence of topological properties. It has been shown that the …
