Two-dimensional flat-bands in Moire-diamonds
Yalan Wei, Shifang Li, Yuke Song +1
The discovery of flat-bands in magic-angle twisted bilayer graphene has underscored the potential of moire engineering for correlated states, but such phases are notoriously diffic…

First-principles predictions of the diversity in atomic structures and electronic properties of the reconstructed Si(111)-7x7 surface
Yuke Song, ShiFang Li, PeiZe Lin +4
The 7x7 reconstruction of Si(111) surface is widely understood by the dimer-adatom-stacking-fault model (DAS), but the predicted metallicity of DAS contradicts experimental signs o…

Observation of Majorana zero modes emerged from topological Dirac semimetal states under uniaxial strain
Quanxin Hu, Shengshan Qin, Yi Peng +12
The topological properties observed in iron-based superconductors extend our understanding of vortex Majorana quasiparticle excitations in unexpected ways. Vortex Majorana physics…
