Quench dynamics and parity blocking in Majorana wires
Suraj Hegde, Vasudha Shivamoggi, Smitha Vishveshwara +1
We theoretically explore quench dynamics in a finite-sized topological fermionic p-wave superconducting wire with the goal of demonstrating that topological order can have marked e…
Weyl Phases in Point-Group Symmetric Superconductors
Vasudha Shivamoggi, Matthew J. Gilbert
We study superconductivity in a Weyl semimetal with broken time-reversal symmetry and stabilized by a point-group symmetry. The resulting superconducting phase is characterized by…
Fractional Spin Josephson Effect and Electrically Controlled Magnetization in Quantum Spin Hall Edges
Qinglei Meng, Vasudha Shivamoggi, Taylor L. Hughes +2
We explore a spin Josephson effect in a system of two ferromagnets coupled by a tunnel junction formed of 2D time-reversal invariant topological insulators. In analogy with the mor…
Edge states and the bulk-boundary correspondence in Dirac Hamiltonians
Roger S. K. Mong, Vasudha Shivamoggi
We present an analytic prescription for computing the edge dispersion E(k) of a tight-binding Dirac Hamiltonian terminated at an abrupt crystalline edge. Specifically, we consider…
