Measuring higher-order bulk topology in a programmable quantum simulator
Pratik Sathe, Niclas Heinsdorf, Majid Kheirkhah +13
Topological insulators lie outside the standard Landau paradigm: Instead of being characterized by local order parameters and spontaneous symmetry breaking, their defining properti…
Analog-Digital Quantum Computing with Quantum Annealing Processors
Rahul Deshpande, Majid Kheirkhah, Chris Rich +12
Quantum annealing processors typically control qubits in unison, attenuating quantum fluctuations uniformly until the applied system Hamiltonian is diagonal in the computational ba…
Phases of three-dimensional -wave superconductors with two attractive interactions
Majid Kheirkhah, Igor F. Herbut
Three-dimensional -wave () superconducting state may result from Cooper pairing in channels with different angular momenta and spin, such as or . W…
Superconductivity in Luttinger semimetals near the SU(4) limit
Majid Kheirkhah, Igor F. Herbut
We consider the spin-3/2 Luttinger fermions with contact attraction near the SU(4)-symmetric limit of vanishing Luttinger spin-orbit-coupling parameter responsible for band inversi…
Sublattice-enriched tunability of bound states in second-order topological insulators and superconductors
Di Zhu, Majid Kheirkhah, Zhongbo Yan
Bound states at sharp corners have been widely viewed as the hallmark of two-dimensional second-order topological insulators and superconductors. In this work, we show that the exi…
Corner- and sublattice-sensitive Majorana zero modes on the kagome lattice
Majid Kheirkhah, Di Zhu, Joseph Maciejko +1
In a first-order topological phase with sublattice degrees of freedom, a change in the boundary sublattice termination has no effect on the existence of gapless boundary states in…
Surface Bogoliubov-Dirac cones and helical Majorana hinge modes in superconducting Dirac semimetals
Majid Kheirkhah, Zheng-Yang Zhuang, Joseph Maciejko +1
In the presence of certain symmetries, three-dimensional Dirac semimetals can harbor not only surface Fermi arcs, but also surface Dirac cones. Motivated by the experimental observ…
Vortex-line topology in iron-based superconductors with and without second-order topology
Majid Kheirkhah, Zhongbo Yan, Frank Marsiglio
The band topology of a superconductor is known to have profound impact on the existence of Majorana zero modes in vortices. As iron-based superconductors with band inversion and $s…
First- and Second-Order Topological Superconductivity and Temperature-Driven Topological Phase Transitions in the Extended Hubbard Model with Spin-Orbit Coupling
Majid Kheirkhah, Zhongbo Yan, Yuki Nagai +1
The combination of spin-orbit coupling with interactions results in many exotic phases of matter. In this Letter, we investigate the superconducting pairing instability of the two-…
Majorana corner flat bands in two-dimensional second-order topological superconductors
Majid Kheirkhah, Yuki Nagai, Chun Chen +1
In this paper we find that confining a second-order topological superconductor with a harmonic potential leads to a proliferation of Majorana corner modes. As a consequence, this r…
