Disorder Effects on the Quasiparticle and Transport Properties of Two-Dimensional Dirac Fermionic Systems
Bo Fu, Yanru Chen, Weiwei Chen +5
Despite extensive existing studies, a complete understanding of the role of disorder in affecting the physical properties of two-dimensional Dirac fermionic systems remains a stand…
On the sample-dependent minimal conductivity in weakly disordered graphene
Weiwei Chen, Yedi Shen, Bo Fu +2
We present a unified understanding of the experimentally observed minimal dc conductivity in weakly disordered graphene. Firstly, based on linear response theory, we reveal that ra…
Spin-orbit related power-law dependence of the diffusive conductivity on the carrier density in disordered Rashba two-dimensional electron systems
Weiwei Chen, Cong Xiao, Qinwei Shi +1
By using the momentum-space Lanczos recursive method which considers rigorously all multiple-scattering events, we unveil that the non-perturbative disorder effect has dramatic imp…
Unusual Metal to Marginal-Metal Transition in Two-Dimensional Ferromagnetic Electron Gases
Weiwei Chen, C. Wang, Qinwei Shi +2
Two-dimensional ferromagnetic electron gases subject to random scalar potentials and Rashba spin-orbit interactions exhibit a striking quantum criticality. As disorder strength …
