Lieb-Schultz-Mattis type theorems for Majorana models with discrete symmetries
Ömer M. Aksoy, Apoorv Tiwari, Christopher Mudry
We prove two Lieb-Schultz-Mattis type theorems that apply to any translationally invariant and local fermionic -dimensional lattice Hamiltonian for which fermion-number conserva…

Stability against contact interactions of a topological superconductor in two-dimensional space protected by time-reversal and reflection symmetries
Ömer M. Aksoy, Jyong-Hao Chen, Shinsei Ryu +2
We study the stability of topological crystalline superconductors in the symmetry class DIIIR and in two-dimensional space when perturbed by quartic contact interactions. It is kno…

Majorana zero modes in a quantum wire platform without Rashba spin-orbit coupling
Ömer M. Aksoy, John R. Tolsma
We propose a platform for engineering helical fermions in a hybridized double-quantum-wire setup. When our setup is proximity coupled to an -wave superconductor it can become a…
