The quest for novel high-temperature superconductors


After nearly three decades of research on high temperature superconductivity, the transition temperature remains stagnant and our understanding incomplete. In this talk, I will argue that finding a novel material system that mimics the cuprate physics can provide a breakthrough. Ruddelsden-popper series iridates display remarkable similarity to high-Tc cuprates in terms of crystal, lattice, and magnetic structures, which lead to similarity in the effective low-energy physics as manifested by the unique cuprate fermiology reproduced in Sr2IrO4. How superconductivity emerges or fails in this new class of materials will reveal essential features of high temperature superconductivity; in particular the long-sought connection between the pseudogap and superconductivity.
