Open AccessEvidence for a three-dimensional quantum spin liquid in PbCuTe2O6
The quantum spin liquid is a highly entangled magnetic state characterized by the absence of static magnetism in its ground state. Instead, the spins fluctuate in a highly correlated way down to the lowest tem...

Similarities between structural distortions under pressure and chemical do** in superconducting BaFe2As2
Fe-based superconductors have attracted tremendous interest recently. New evidence on BaFe2As2 shows that chemical do** and pressure, both of which induce superconductivity, distort the lattice in similar ways....
