Title: Topological states in A15 superconductors

Abstract

Superconductors with the A15 structure are prototypical type-II s-wave superconductors which have generated considerable interest in early superconducting material history. Yet, the topological nature of the electronic structure remains unnoticed so far. In this work, using first-principles band structure calculations based on density-functional theory, we show that the A15 superconductors (Ta₃Sb, Ta₃Sn, and Ta₃Pb) have nontrivial band topology in the bulk electronic band structures, leading to the formation of topological surface states near the Fermi energy. Due to the bulk superconductivity, the proximity effect in the topological surface states would induce topological superconductivity even without heterostructure of a topological insulator and an s-wave superconductor. Our results indicate that the A15 superconductors are promising candidates for the realization of the topological superconductivity and the Majorana fermion.

Phase-Slip Lines and Anomalous Josephson Effects in Tungsten Nanoscale Cluster-Based Topological Insulator Nanobridges: Implications for Topologically Protected Qubits and Quantum Sensors

Journal Article Qu, Dong-Xia ; Cuozzo, Joseph J. ; Teslich, Nick E. ; ... - ACS Applied Nano Materials

Superconducting topological systems formed by a strong 3D topological insulator (TI) in proximity to a conventional s-wave superconductor (SC) have been intensely studied, as they may host Majorana zero modes. However, there are limited experimental realizations of TI-SC systems in which robust superconducting pairing is induced on the surface states of the TI and a topological superconducting state is established. Here, we fabricate a TI-SC system by depositing, via a focused ion beam, tungsten (W) nanoscale clusters on the surface of TI Bi_0.91Sb_0.09. We find that the resulting heterostructure supports phase-slip lines (PSLs) that act as effective Josephson junctions (JJs).more »« less

Boundary-Obstructed Topological High- $T_{c}$ Superconductivity in Iron Pnictides

Journal Article Wu, Xianxin ; Benalcazar, Wladimir A. ; Li, Yinxiang ; ... - Physical Review. X

Nontrivial topology and unconventional pairing are two central guiding principles in the contemporary search for and analysis of superconducting materials and heterostructure compounds. Previously, a topological superconductor has been predominantly conceived to result from a topologically nontrivial band subject to an intrinsic or external superconducting proximity effect. Furthermore, we propose a new class of topological superconductors that are uniquely induced by unconventional pairing. They exhibit a boundary-obstructed higher-order topological character and, depending on their dimensionality, feature unprecedently robust Majorana bound states or hinge modes protected by chiral symmetry. We predict the 112 family of iron pnictides, such as Ca_1–xLa_xFeAs₂, tomore »« less

Massive Suppression of Proximity Pairing in Topological ${({Bi}_{1 - x} {Sb}_{x})}_{2} {Te}_{3}$ Films on Niobium

Journal Article Hlevyack, Joseph A. ; Najafzadeh, Sahand ; Lin, Meng-Kai ; ... - Physical Review Letters

Interfacing bulk conducting topological Bi₂Se₃ films with s-wave superconductors initiates strong superconducting order in the nontrivial surface states. Yet, bulk insulating topological (Bi_1-xSb_x)₂Te₃ films on bulk Nb instead exhibit a giant attenuation of surface superconductivity, even for films only two-layers thick. This massive suppression of proximity pairing is shown by ultrahigh-resolution band mappings and by contrasting quantified superconducting gaps with those of heavily n-doped topological Bi₂Se₃/Nb. The results underscore the limitations of using superconducting proximity effects to realize topological superconductivity in nearly intrinsic systems.

Monolayer Superconductivity and Tunable Topological Electronic Structure at the Fe(Te,Se)/Bi₂Te₃ Interface

Journal Article Moore, Robert G. ; Lu, Qiangsheng ; Jeon, Hoyeon ; ... - Advanced Materials

Abstract The interface between 2D topological Dirac states and an s ‐wave superconductor is expected to support Majorana‐bound states (MBS) that can be used for quantum computing applications. Realizing these novel states of matter and their applications requires control over superconductivity and spin‐orbit coupling to achieve spin‐momentum‐locked topological interface states (TIS) which are simultaneously superconducting. While signatures of MBS have been observed in the magnetic vortex cores of bulk FeTe _0.55 Se _0.45 , inhomogeneity and disorder from doping make these signatures unclear and inconsistent between vortices. Here superconductivity is reported in monolayer (ML) FeTe _1–y Se _y (Fe(Te,Se)) grownmore »« less

Nontrivial Fermi surface topology of the kagome superconductor CsV₃Sb₅ probed by de Haas–van Alphen oscillations

Journal Article Shrestha, K. ; Chapai, R. ; Pokharel, Bal K. ; ... - Physical Review. B

Here, we have investigated the normal state Fermi-surface properties of the kagome superconductor CsV₃Sb₅ using torque magnetometry with applied fields (H) up to 35 T. The torque signal shows clear de Haas-van Alphen (dHvA) oscillations above 15 T. The oscillations are smooth and consist of seven distinct frequencies with values from similar to ~18 T to 2135 T. The presence of higher frequencies in CsV₃Sb₅ is further confirmed by carrying out additional measurements using the tunnel diode oscillator technique. All frequencies measured at different tilt angles (θ) of the field direction with respect to the c axis show a 1/cosθmore »« less
