We study the phase diagram of a model quantum spin Hall system as a function of band
inversion and band-coupling strength, demonstrating that when band hybridization is weak …

Motivated by experiments on the double perovskites La 2 ZnIrO 6 and La 2 MgIrO 6, we
study the magnetism of spin-orbit coupled j eff= 1/2 iridium moments on the three …

We consider a magnetic skyrmion crystal formed at the surface of a topological insulator.
Incorporating the exchange interaction between the helical Dirac surface states and the …

We study a class of multiorbital models based on those proposed by Venderbos et al.[Phys.
Rev. B 98, 235160 (2018) 2469-9950 10.1103/PhysRevB. 98.235160] which exhibit an …

The interplay between topology and correlation lies at the forefront of modern condensed
matter physics. In this paper, we study the extended fermion-Hubbard model, including the …

Topological phases with broken time-reversal symmetry and Chern number| C|≥ 2 are of
fundamental interest, but it remains unclear how to engineer the desired topological …

We study a special class of topological phase transitions in two dimensions described by the
inversion of bands with relative angular momentum higher than 1. A band inversion of this …

The study of Weyl semimetals (WSMs) lies at the forefront of the nontrivial topological
phenomena in condensed-matter physics. In this work, we study the effect of on-site …

For two-dimensional single-valley quadratic band crossing systems with weak repulsive
electron-electron interactions, we show that upon introducing a chemical potential, particle …

We show a tight-binding model for double perovskite monolayers grown in the {001}
crystallographic direction can exhibit higher Chern numbers for the lowest band of the model …
