Delocalization of Quasiparticle Moiré States in Twisted Bilayer hBN
Arsineh Apelian, Annabelle Canestraight, Songyuan Liu +1
Twisted bilayers host many emergent phenomena in which the electronic excitations (quasiparticles - QPs) are closely intertwined with the local stacking order. By inspecting twiste…

Reduced scaling of optimal regional orbital localization via sequential exhaustion of the single-particle space
Guorong Weng, Mariya Romanova, Arsineh Apelian +2
Wannier functions have become a powerful tool in the electronic structure calculations of extended systems. The generalized Pipek-Mezey Wannier functions exhibit appealing characte…
