Quantum Skyrmion Lattices in Heisenberg Ferromagnets
Andreas Haller, Solofo Groenendijk, Alireza Habibi +2
Skyrmions are topological magnetic textures that can arise in non-centrosymmetric ferromagnetic materials. In most systems experimentally investigated to date, skyrmions emerge as…
Kerr and Faraday rotations in topological flat and dispersive band structures
Alireza Habibi, Ahmad Z. Musthofa, Elaheh Adibi +3
Integer quantum Hall (IQH) states and quantum anomalous Hall (QAH) states show the same static (dc) response but distinct dynamical (ac) response. In particular, the ac anomalous H…
Optical conductivity of triple point fermions
Alireza Habibi, Tohid Farajollahpour, S. A. Jafari
As a low-energy effective theory on non-symmorphic lattices, we consider a generic triple point fermion Hamiltonian which is parameterized by an angular parameter . We find stro…
Phase transitions in the binary-alloy Hubbard model: insight from strong-coupling perturbation theory
Elaheh Adibi, Alireza Habibi, S. A. Jafari
In the binary-alloy with composition AB of two atoms with ionic energy scales , an apparent Ander- son insulator (AI) is obtained as a result of randomness in the…
Topological phase diagram of the disordered 2XY model in presence of generalized Dzyaloshinskii-Moriya Interaction
Alireza Habibi, Rasoul Ghadimi, S. A. Jafari +1
Topological index of a system specifies gross features of the system. However, in situations such as strong disorder where by level repulsion mechanism the spectral gap is closed,…
Strong-coupling perturbative study of the disordered Hubbard model on honeycomb lattice
Alireza Habibi, Elaheh Adibi, S. A. Jafari
We study the Anderson disordered Hubbard model on the honeycomb lattice. The Hubbard term is han- dled with strong-coupling perturbation theory which encodes the Mott transition ph…
Resilience of Majorana Fermions in the face of Disorder
Alireza Habibi, S. A. Jafari, S. Rouhani
We elucidate the reduction of the winding number (WN) caused by the onsite disorder in a higher WN next nearest neighbor XY model. When disorder becomes strong enough, Majorana edg…
RKKY interaction in heavily vacant graphene
Alireza Habibi, S. A. Jafari
Dirac electrons in clean graphene can mediate the interactions between two localized magnetic moments. The functional form of the RKKY interaction in pristine graphene is specified…
