Summary: The research on surface Andreev bound states in superfluid He-3 demonstrates that they are fragile with respect to the details of surface scattering, unlike the robust surface/edge states in topological insulators and quantum Hall systems. The unexpectedly large suppression of T-c due to surface magnetic scattering leads to an increased density of low energy bound states.

Summary: Researchers propose a novel approach to achieve emergent quasi-one-dimensional TSCs in unconventional superconductors through naturally embedded quantum structures like atomic line defects. The mixed-parity spin pairing of neighboring electrons at the line defect results in nontrivial topological invariants, creating TSCs with robust Majorana zero modes.

Summary: Experimental findings show that a new type of superconductivity can be observed at the point contacts of Bi2Se3 topological insulator, which can be erased through thermal cycles and induced again by applying voltage pulses at low temperatures, suggesting significance for designing new types of quantum devices.

Summary: Spin-orbit effects in topological insulators and at Rashba interfaces have led to various newly discovered effects. In this study, a bilinear magnetoresistance phenomenon was observed in strained HgTe, and its amplitude and sign could be controlled by adjusting the contributions from opposite surfaces using an electric gate.

Summary: This review systematically studies recent advances in topological superconductivity, including both bulk systems and heterostructures. The relationship between Majorana fermions and topological superconductors and heterostructures is described, along with key experimental techniques for characterizing candidates for topological superconductivity. The potential materials that may demonstrate topological superconductivity are summarized, as well as the effects of pressure and muon spin rotation studies.

Summary: In this study, the physics of the Josephson effect in odd-parity nematic superconductors is investigated. It is found that the interaction between nematicity and crystallographic axes in the superconductors leads to an unusual Josephson effect, which can be observed without any magnetization and exhibits an anomalous Josephson Hall effect.

Summary: The study investigates the spin-orbit torques (SOTs) and spin Hall magnetoresistance generated by Bi0.9Sb0.1(0001) when coupled with FeCo, confirming its effectiveness as a spin-injector material. The research finds that charge-to-spin conversion in single-crystal Bi0.9Sb0.1(0001) is isotropic despite the strong anisotropy of the topological surface states. Additionally, the damping-like SOT displays non-monotonic temperature dependence, with a minimum occurring at 20 K.

Summary: CaBi2 has been experimentally confirmed as a superconductor with a transition temperature of 2 K, and identified as a topological insulator through spin- and angle-resolved photoemission spectroscopy, providing a potential platform for studying the interplay between superconductivity and topology. However, the detailed transport properties of CaBi2 single crystal have not been explored. In this study, the magneto-transport properties of CaBi2 single crystal grown by a flux method were systematically investigated, revealing a magnetic-field-induced upturn behavior with a plateau in resistivity at low temperature. Additionally, an extremely large and non-saturating magnetoresistance up to approximately 15000% at 3 K and 12 T was achieved.

Summary: In this work, we present a detailed modeling approach for a topological insulator nanoribbon in contact with a superconductor, inducing superconductivity. Our simulation results indicate that a top-proximitized TI nanoribbon is ideal for realizing fully gapped topological superconductivity, especially when the Fermi level is near the Dirac point, resulting in robust quantized zero-bias conductance peak.

Summary: The discovery of 31 2D tellurium allotropes with different cohesive energies and properties, including semiconductors, topological insulators, and superconductors, enriches the field of 2D elemental materials. One of these allotropes exhibits both topological and superconducting properties, which is unique in the reported elemental 2D materials. This research provides rich possibilities for exploring novel functionalities for future device applications.

Summary: The study reports the growth and magneto-transport studies of Pd3Bi2S2 thin films, reducing the mobility of bulk carriers and revealing contributions from 2-dimensional topological surface states for the first time. The analysis of magnetotransport data suggests multiple conduction channels contribute to the transport, and electron-phonon scattering also plays a role in the phase relaxation mechanism in PBS films.

Summary: In this study, we demonstrate that symmetry-protected topological (SPT) phases can also be applied to average symmetries, where local quenched disorders break the symmetries but restore them upon disorder averaging. We classify and characterize a large class of average SPT phases using a decorated domain wall approach, and show that the boundary states of such phases will almost certainly be long-range entangled. We also develop a theory for generalized average SPT phases based on density matrices and quantum channels, indicating that topological quantum phenomena associated with average symmetries can be as rich as those with exact symmetries.
