DOI: 10.1103/74gh-tjmq
Abstract: Geometric frustration has long been a subject of enduring interest in condensed matter physics. While geometric frustration traditionally focuses on magnetic systems, little attention is paid to the"frustrated superconductivity"which could arise when the superconducting interaction… read more here.

DOI: 10.1103/physrevb.100.054501
Abstract: The symmetry-based phenomenological theory of Cooper pairing is a powerful tool in the studies of unconventional superconductors. At the heart of this theory is the assumption that the electron Bloch states transform under crystal symmetry… read more here.

DOI: 10.1126/sciadv.aar7214
Abstract: Bismuth selenide becomes superconducting upon coupling to metallic niobium, and its topological states pair up to form a gap. A topological insulator film coupled to a simple isotropic s-wave superconductor substrate can foster helical pairing… read more here.
