Semiclassical transport with Berry curvature: Chambers formula and applications to systems with Fermi surface topological transitions
نویسندگان
چکیده
Starting with general semiclassical equations of motion for electrons in the presence electric and magnetic fields, we extend Chambers formula to include addition a field, time-dependent fields bands Berry curvature. We thereby compute conductivity tensor ${\sigma}_{{\alpha}{\beta}}(B,{\omega})$ field two (2D) three (3D) dimensions focus then on several applications magnetotransport metals Fermi surface topological transitions 2D. In particular, consider rectangular lattice model related overdoped graphene, investigate signatures different types Hall coefficient, ${\sigma}_{xy}$ longitudinal ${\sigma}_{xx}$. The behavior those quantities as function frequency, when is time dependent, also investigated. As an example non-zero curvature, study Haldane within this context. addition, provide linear nonlinear current order $E^2$.

متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
