Second-order topological insulator and fragile topology in topological circuitry simulation
Ce Shang, Xiaoning Zang, Wenlong Gao +2
Second-order topological insulators (SOTIs) are the topological phases of matter in d dimensions that manifest (d-2)-dimensional localized modes at the intersection of the edges. W…
Identification and Resolution of Unphysical Multielectron Excitations in the Real-Time Time-Dependent Kohn-Sham Formulation
Xiaoning Zang, Udo Schwingenschlogl, Mark T. Lusk
We resolve a fundamental issue associated with the conventional Kohn-Sham formulation of real-time time-dependent density functional theory. We show that unphysical multielectron e…
Artificial gauge fields and topological insulators in Moire superlattices
Ce Shang, Adel Abbout, Xiaoning Zang +2
We propose an innovative quantum emulator based on Moire superlattices showing that, by employing periodical modulation on each lattice site, one can create tunable, artificial gau…
Angular momentum transport with twisted exciton wave packets
Xiaoning Zang, Mark T. Lusk
A chain of cofacial molecules with CN or CNh symmetry supports excitonic states with a screw-like structure. These can be quantified with the combination of an axial wavenumber and…
