The quasi-two-dimensional kagome materials AV3Sb5 (A= K, Rb, Cs) were found to be a
prime example of kagome superconductors, a new quantum platform to investigate the …

Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …

Vortices in topological superconductors may host Majorana zero modes (MZMs), which have
been proposed as the building blocks of fault-tolerant topological quantum computers …

High-temperature superconductivity and a wide variety of exotic superconducting states
discovered in FeSe-based materials have been at the frontier of research on condensed …

We show, theoretically, that a heterostructure of monolayer FeTe 1-x Se x—a
superconducting quantum spin Hall material—with a monolayer of FeTe—a bicollinear …

Phonons are an ideal platform for realizing stable spinless two-dimensional (2D) Dirac
points because they have a bosonic nature and hard-to-break time-reversal symmetry. It …

Nontrivial topology and unconventional pairing are two central guiding principles in the
contemporary search for and analysis of superconducting materials and heterostructure …

The iron-based superconductor FeTe x Se1− x is one of the material candidates hosting
Majorana vortex modes residing in the vortex cores. It has been observed by recent …

In the presence of both space and time reversal symmetries, an s-wave A 1 g
superconducting state is usually topologically trivial. Here, we demonstrate that an exception …

Generally, the topological corner state in two-dimensional (2D) second-order topological
insulator (SOTI) is equivalent to the well-known domain wall state, which is originated from …
