Clarifying the origin of chain superconductivity in Y-based cuprates:why does...
YBa2Cu4O8 is a special member of the Y-based High-Tc cuprate superconductors since it exhibits two CuO chains per unit cell, compared to the single CuO chain per unit cell... -

BiPd is a Type-II superconductor with a non-centrosymmetric crystal structure. Accommodating this lack of inversion symmetry requires that the superconducting order parameter... -
Resolving the spin and orbital part of the Sr2RuO4 superconducting order para...
Stronthium ruthenate (SRO) has long been considered a paradigm for p-wave superconductivity, but recent results have raised important questions in this regard. These include... -
