Magnetic Field Response and Chiral Symmetry of Time Reversal Invariant Topological Superconductors
Eugene Dumitrescu, Jay D. Sau, Sumanta Tewari
We study the magnetic field response of the Majorana Kramers pairs of a one-dimensional time-reversal invariant (TRI) superconductors (class DIII) with or without a coexisting chir…
Mean field theory of competing orders in metals with antiferromagnetic exchange interactions
Jay Deep Sau, Subir Sachdev
It has long been known that two-dimensional metals with antiferromagnetic exchange interactions have a weak-coupling instability to the superconductivity of spin-singlet, d-wave el…
Enhanced anti-ferromagnetic exchange between magnetic impurities in a superconducting host
Norman Y. Yao, Leonid I. Glazman, Eugene A. Demler +2
It is generally believed that superconductivity only weakly affects the indirect exchange between magnetic impurities. If the distance r between impurities is smaller than than the…
Density of states of disordered topological superconductor-semiconductor hybrid nanowires
Jay D. Sau, S. Das Sarma
Using Bogoliubov-de Gennes (BdG) equations we numerically calculate the disorder averaged density of states of disordered semiconductor nanowires driven into a putative topological…
