Relaxation and domain wall structure of bilayer moire systems
Paul Cazeaux, Drake Clark, Rebecca Engelke +2
Moire patterns result from setting a 2D material such as graphene on another 2D material with a small twist angle or from the lattice mismatch of 2D heterostructures. We present a…

On the Su-Schrieffer-Heeger model of electron transport: low-temperature optical conductivity by the Mellin transform
Dionisios Margetis, Alexander B. Watson, Mitchell Luskin
We describe the low-temperature optical conductivity as a function of frequency for a quantum-mechanical system of electrons that hop along a polymer chain. To this end, we invoke…
