The authors study (Bi,Sb)₂Te₃/FeTe bilayers, which feature emergent superconductivity at the interface with T_c ~ 12 K. Through angle-resolved photoemission spectroscopy and electrical transport measurements, they argue that the Dirac-fermion-mediated Ruderman-Kittel-Kasuya-Yosida-type interaction weakens antiferromagnetic order in FeTe layer, allowing for superconductivity.

Using molecular-beam epitaxy, we synthesize heterostructures of topological insulator Bi₂Se₃ and the Ising superconductor monolayer NbSe₂. By changing the Bi₂Se₃ thickness, they demonstrate a crossover from Ising- to Rashba-type superconducting pairing.

Altermagnets combine the rapid dynamics and zero magnetization of collinear antiferromagnets with the spin-splitting of ferromagnets, making them an idea platform for both fundamental research and applications. Here, Yang, Li and coauthors map the large altermagnetic spin-splitting in CrSb located near the Fermi level.

An altermagnet has highly anisotropic spin splitting but zero net magnetization. Here, S.-B. Zhang et al. theoretically study the behavior of s-wave superconductor/altermagnet hybrid structures, finding that Cooper pairs in the proximitized altermagnet have an anisotropic non-zero momentum.

The authors propose that screw or edge dislocations can trap Majorana zero modes in the absence of an external magnetic field. They predict that the Majoranas will appear as second-order topological modes on the four corners of an embedded 2D subsystem defined by the cutting plane of the dislocation.

It is widely believed that bulk-state topology is crucial for enabling Majorana zero modes in solid-state systems. Here, the authors predict that superconducting vortices containing Majorana zero modes can arise from topologically-trivial electronic bands, expanding the pool of materials which may host such phenomena.

The underlying symmetry of a given system dictates the material properties from the electronic band structure to its spontaneous symmetry broken ordering. Here, the authors consider the effects of symmetry breaking and investigate spin-singlet orbital triplet pairings in unconventional superconductors with electronic nematicity, they apply their results to iron-based superconductors and twisted bilayer graphene.

Topological superconductors are deemed to carry great potential of realizing non-Abelian states for fault-tolerant quantum computing. Here, the authors propose a new theoretical mechanism to attain topological superconductivity via forward phonon scattering and hence provide a new possibility for engineering high-temperature topological superconductors.

Topological superconductors possess Majorana modes at the edge and are important in future quantum computational devices. The authors theoretically demonstrate the Larkin-Ovchinnikov superconducting phase can be topologically non-trivial in certain sandwich structure or iron-based superconductor films and possess a chain of Majorana modes.
