Chiral superconductors are a unique class of unconventional superconductors in which the complex superconducting order parameter winds clockwise or anticlockwise in the momentum space. It represents a topologically non-trivial system with intrinsic time-reversal symmetry breaking (TRSB) and direct implications for topological quantum computing. Chiral molecules with neither mirror nor inversion symmetry have been widely investigated. An international team of researchers (USA – UCLA, Czech Republic) explored unconventional superconductivity in chiral molecule intercalated TaS2 hybrid superlattices. The experimental signatures of unconventional superconductivity suggested that the intriguing interplay between crystalline atomic layers and the self-assembled chiral molecular layers may lead to exotic topological materials. According to the researchers their study highlights that hybrid superlattices could lay a versatile path to artificial quantum materials by combining a vast library of layered crystals of rich physical properties with the nearly infinite variations of molecules of designable structural motifs and functional groups… read more.
