Epitaxial engineering of solid state heterointerfaces is a leading avenue to realizing
enhanced or novel electronic states of matter. As a recent example, bulk FeSe is an …

The Majorana fermion, which is its own antiparticle and obeys non-Abelian statistics, plays a
critical role in topological quantum computing. It can be realized as a bound state at zero …

The Majorana fermions/quasi-particles obey non-Abelian statistics and play an essential
role in topological quantum computing. Theoretically, they can be realized as a zero-energy …

Superconductivity arises from two distinct quantum phenomena: electron pairing and long-
range phase coherence. In conventional superconductors, the two quantum phenomena …

Iron pnictides are the only known family of unconventional high-temperature
superconductors besides cuprates. Until recently, it was widely accepted that …

Finding a new derivative structure of FeSe-based superconductors with a high
superconducting transition temperature (T c) is of great significance. Here, in this work, an …

The energy and spatial distributions of vortex bound state in superconductors carry
important information about superconducting pairing and the electronic structure. Although …

The iron-based superconductors are an ideal platform to reveal the enigma of the
unconventional superconductivity and potential topological superconductivity. Among them …

We report a high-pressure study on the heavily electron doped L i 0.36 (NH 3) y F e 2 S e 2
single crystal by using a cubic anvil cell apparatus. The superconducting transition …

In this article, we review the recent significant progress in the theoretical studies of the
electronic states by mainly focusing on Fe-based and cuprate superconductors. These …
