The search for Majorana fermions in topological superconductors is one of paramount
research targets in physics today. Using a cryogenic scanning tunneling microscopy, we …

Magnetic flux quantization is one of the defining properties of a superconductor. We report
the observation of half-integer magnetic flux quantization in mesoscopic rings of …

The nature of the superconducting state in kagome metals AV 3 Sb 5 is a key issue in need
of experimental clarification. Here, we report on a study of the superconducting order …

A supercurrent flowing in a superconductor meets no resistance. Yet an electric field may
still be established within the superconductor in the presence of dissipative processes, such …

Both α-PdB i 2 and β-PdB i 2 are superconductors with topological nontrivial signs. Here we
report that the α-PdB i 2 superconductor is converted by pressure into the β-phase …

We report first-principles calculations of the superconducting properties of β-Bi 2 Pd within
the fully anisotropic Migdal-Eliashberg formalism. We find a single anisotropic …

We report measurements of the in-plane London penetration depth λ in single crystals of the
α-PdBi 2 superconductor—the α-phase counterpart of the putative topological …

Topological superconductor (TSC) hosting Majorana fermions has been established as a
milestone that may shift our scientific trajectory from research to applications in topological …

A first-order-like resistivity hysteresis is induced by a subtle structural transition under
hydrostatic pressure in the topological nodal-line superconductor PbTaSe 2. This structure …

Interest in topological states of matter burgeoned over a decade ago with the theoretical
prediction and experimental detection of topological insulators, especially in bulk three …
