Sign structure of the -- model and its physical consequences
Xin Lu, Jia-Xin Zhang, Shou-Shu Gong +2
Understanding the doped Mott insulator is a central challenge in condensed matter physics. In this work, we first explicitly identify a new sign structure in the -- model…

Local density of state oscillations in laterally heterostructured topological insulator-semiconductor systems
David J. Alspaugh, D. N. Sheng, Mahmoud M. Asmar
We study local density of state (LDOS) oscillations arising from the scattering of electrons at atomic edge defects in topological insulator (TI) surfaces. To create edge scatterin…
