Crystalline symmetry protected helical Majorana modes in the iron pnictides

17 Apr 2019 König Elio J. Coleman Piers

We propose that propagating one-dimensional Majorana fermions will develop in the vortex cores of certain iron-based superconductors, most notably Li(Fe$_{1-x}$Co$_x$)As. A key ingredient of this proposal are the 3D Dirac cones recently observed in ARPES experiments [P. Zhang et al., Nat... (read more)
