Open AccessDual topological states in the layered titanium-based oxypnictide superconductor BaTi2Sb2O
Topological superconductors have long been predicted to host Majorana zero modes which obey non-Abelian statistics and have potential for realizing non-decoherence topological quantum computation. However, mat...

Open AccessFormation of As-As Interlayer Bonding in the collapsed tetragonal phase of NaFe2As2 under pressure
NaFe2As2 is investigated experimentally using powder x-ray diffraction and Raman spectroscopy at pressures up to 23 GPa at room temperature and using ab-initio calculations. The results reveal a pressure-induced ...

Open AccessElectronic and magnetic phase diagram in KxFe2-ySe2 superconductors
The correlation and competition between antiferromagnetism and superconductivity are one of the most fundamental issues in high temperature superconductors. Superconductivity in high temperature cuprate superc...
