Detrimental effects of disorder in two-dimensional time-reversal invariant topological superconductors
Mahdi Mashkoori, Fariborz Parhizgar, Stephan Rachel +1
The robustness against local perturbations, as long as the symmetry of the system is preserved, is a distinctive feature of topological quantum states. Magnetic impurities and defe…
Origin of Topological Surface Superconductivity in FeSeTe
Eric Mascot, Sagen Cocklin, Martin Graham +3
The engineering of Majorana zero modes in topological superconductors, a new paradigm for the realization of topological quantum computing and topology-based devices, has been hamp…
Identification of topological superconductivity in magnetic impurity systems using bulk spin-polarization
Mahdi Mashkoori, Saurabh Pradhan, Kristofer Björnson +2
Magnetic impurities on the surface of spin-orbit coupled but otherwise conventional superconductors provide a promising way to engineer topological superconductors with Majorana bo…
Majorana bound states in magnetic impurity chains: effects of -wave pairing
Mahdi Mashkoori, Annica Black-Schaffer
We consider an atomic chain of magnetic impurities on the surface of a spin-orbit coupled superconductor with a dominating -wave and sub-dominating -wave order parameters. In…
Impact of topology on the impurity effects in extended -wave superconductors with spin-orbit coupling
M. Mashkoori, A. G. Moghaddam, M. H. Hajibabaee +2
We investigate the impact of topology on the existence of impurity subgap states in a time-reversal-invariant superconductor with an extended -wave pairing and strong spin-orbit…
Impurity bound states in fully gapped -wave superconductors with subdominant order parameters
Mahdi Mashkoori, Kristofer Björnson, Annica M. Black-Schaffer
Impurities in superconductors and their induced bound states are important both for engineering novel states such as Majorana zero-energy modes and for probing bulk properties of t…
Localized magnetic states in three dimensional Dirac solids
M. Mashkoori, I. Mahyaeh, S. A. Jafari
Formation of localized magnetic states in a metallic host is a classic problem ofcondensed matter physics formalized by P. W. Anderson within the so called single impurity Anderson…
Stable local moments of vacancies and hollow-site impurities in graphene
M. Mashkoori, S. A. Jafari
Taking into account the possibility of a p-wave hybridization function of ad-atom with Dirac electrons in graphene -- which arises for vacancies and hollow-site impurit…
Phase diagram of the strongly correlated Kane-Mele-Hubbard model
Abolhassan Vaezi, Mahdi Mashkoori, Mehdi Hosseini
We explore the phase diagram of the strongly correlated Hubbard model with intrinsic spin orbit coupling on the honeycomb lattice. We obtain the low energy effective model describi…
