متن کاملTopological quantum numbers in the Hall effect
Topological quantum numbers account for the precise quantization that occurs in the integer Hall effect. In this theory, Kubo’s formula for the conductance acquires a topological interpretation in terms of Chern numbers and their non-commutative analog, the Fredholm Indices.
متن کاملSpin-Orbit Coupling in Polariton Graphene: Optical Spin Hall Effect and Z Topological Insulator
We show that the TE-TM splitting of planar cavities leads to a special type of spin-orbit coupling for polariton graphene, a honeycomb superstructure formed by pillar microcavities, transforming into an emergent field with Dresselhaus symmetry at the Dirac points of the Brillouin zone. This transformation can be evidenced by the Optical Spin Hall effect. Under an applied magnetic field, polarit...
متن کاملWeak hyper semi-quantales and weak hypervalued topological spaces
The purpose of this paper is to construct a weak hyper semi-quantale as a generalization of the concept of semi-quantale and used it as an appropriate hyperlattice-theoretic basis to formulate new lattice-valued topological theories. Based on such weak hyper semi-quantale, we aim to construct the notion of a weak hypervalued-topology as a generalized form of the so-called lattice-valued t...
متن کاملRobustness of topological Hall effect of nontrivial spin textures
We analyze the topological Hall conductivity (THC) of topologically nontrivial spin textures like magnetic vortices and skyrmions and investigate its possible application in the readback for magnetic memory based on those spin textures. Under adiabatic conditions, such spin textures would theoretically yield quantized THC values, which are related to topological invariants such as the winding n...
