Efficient Computation of Kubo Conductivity for Incommensurate 2D Heterostructures
Daniel Massatt, Stephen Carr, Mitchell Luskin
Here we introduce a numerical method for computing conductivity via the Kubo Formula for incommensurate 2D bilayer heterostructures using a tight-binding framework. We begin with d…

Angle-Dependent {\it Ab initio} Low-Energy Hamiltonians for a Relaxed Twisted Bilayer Graphene Heterostructure
Shiang Fang, Stephen Carr, Ziyan Zhu +2
We present efficient angle-dependent low-energy Hamiltonians to describe the properties of the twisted bilayer graphene (tBLG) heterostructure, based on {\it ab initio} calculation…

Modeling and Computation of Kubo Conductivity for 2D Incommensurate Bilayers
Simon Etter, Daniel Massatt, Mitchell Luskin +1
This paper presents a unified approach to the modeling and computation of the Kubo conductivity of incommensurate bilayer heterostructures at finite temperature. Firstly, we derive…
