Phonon-limited resistivity of multilayer graphene systems
Seth M. Davis, Sage B. Brooks, Yang-Zhi Chou +2
We calculate the theoretical contribution to the doping and temperature () dependence of electrical resistivity due to scattering by acoustic phonons in Bernal bilayer graphene…
Hofstadter butterfly and Floquet topological insulators in minimally twisted bilayer graphene
Yang-Zhi Chou, Fengcheng Wu, Sankar Das Sarma
We theoretically study the Hofstadter butterfly of a triangular network model in minimally twisted bilayer graphene (mTBLG). The band structure manifests periodicity in energy, mim…
Topological Protection from Random Rashba Spin-Orbit Backscattering: Ballistic Transport in a Helical Luttinger Liquid
Hong-Yi Xie, Heqiu Li, Yang-Zhi Chou +1
The combination of Rashba spin-orbit coupling and potential disorder induces a random current operator for the edge states of a 2D topological insulator. We prove that charge trans…
Helical Quantum Edge Gears in 2D Topological Insulators
Yang-Zhi Chou, Alex Levchenko, Matthew S. Foster
We show that two-terminal transport can measure the Luttinger liquid (LL) parameter , in helical LLs at the edges of two dimensional topological insulators (TIs) with Rashba spi…
Surface transport coefficients for three-dimensional topological superconductors
Hong-Yi Xie, Yang-Zhi Chou, Matthew S. Foster
We argue that surface spin and thermal conductivities of three-dimensional topological superconductors are universal and topologically quantized at low temperature. For a bulk wind…
