Equivalence of topological mirror and chiral superconductivity in one dimension
Eugene Dumitrescu, Gargee Sharma, Jay D. Sau +1
Recently it has been proposed that a unitary topological mirror symmetry can stabilize multiple zero energy Majorana fermion modes in one dimensional (1D) time reversal (TR) invari…
Hidden Symmetry Decoupling of Majorana Fermions
E. Dumitrescu, T. D. Stanescu, S. Tewari
Multiple zero-energy Majorana fermions (MFs) with spatially overlapping wave functions can survive only if their splitting is prevented by an underlying symmetry. Here we show that…
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…
Topological Properties of Time Reversal Symmetric Kitaev Chain and Applications to Organic Superconductors
E. Dumitrescu, Sumanta Tewari
We show that the pair of Majorana modes at each end of a 1D spin triplet superconductor with total Cooper pair spin S_x=0 (i.e., Delta_{up,up} = -Delta_{down,down} = p*Delta_0; two…
Topological thermoelectric effects in spin-orbit coupled electron and hole doped semiconductors
E. Dumitrescu, Chuanwei Zhang, D. C. Marinescu +1
We compute the intrinsic contributions to the Berry-phase mediated anomalous Hall and Nernst effects in electron- and hole-doped semiconductors in the presence of an in-plane magne…
Hole-doped semiconductor nanowire on top of an s-wave superconductor: A new and experimentally accessible system for Majorana fermions
Li Mao, Ming Gong, E. Dumitrescu +2
Majorana fermions were envisioned by E. Majorana in 1935 to describe neutrinos. Recently it has been shown that they can be realized even in a class of electron-doped semiconductor…
