Large Josephson current in Weyl nodal loop semimetals due to odd-frequency superconductivity
Fariborz Parhizgar, Annica M. Black-Schaffer
Weyl nodal loop semimetals (WNLs) host a closed nodal line loop Fermi surface in the bulk, protected zero-energy flat band, or drumhead, surface states, and strong spin-polarizatio…
Odd-frequency pairing in a superconductor coupled to two parallel nanowires
Christopher Triola, Annica M. Black-Schaffer
We study the behavior of Cooper pair amplitudes that emerge when a two-dimensional superconductor is coupled to two parallel nanowires, focusing on the conditions for realizing odd…
Majorana bound states in magnetic impurity chains: effects of -wave pairing
Mahdi Mashkoori, Annica Black-Schaffer
We consider an atomic chain of magnetic impurities on the surface of a spin-orbit coupled superconductor with a dominating -wave and sub-dominating -wave order parameters. In…
Majorana bound state localization and energy oscillations for magnetic impurity chains on conventional superconductors
Andreas Theiler, Kristofer Björnson, Annica M. Black-Schaffer
We study a chain of magnetic impurities on a conventional superconductor with spin-orbit coupling, treating the superconducting order fully self-consistently. We find and quantify…
Gap oscillations and Majorana bound states in magnetic chains on superconducting honeycomb lattices
Raphael L. R. C. Teixeira, Dushko Kuzmanovski, Annica M. Black-Schaffer +1
Magnetic chains on superconducting systems have emerged as a platform for realization of Majorana bound states (MBSs) in condensed matter systems with possible applications to topo…
Finite length effect on supercurrents between trivial and topological superconductors
Jorge Cayao, Annica M. Black-Schaffer
We numerically analyze the effect of finite length of the superconducting regions on the low-energy spectrum, current-phase curves, and critical currents in junctions between trivi…
