چکیده
A theoretical framework is outlined for calculating the spin-Chern number of topological Dirac semimetals and quantum spin Hall insulators lacking spin-conservation law gapless edge modes. Spin-charge separation quantized spin-pumping are probed by inserting a magnetic flux tube.

Classification of stable three-dimensional Dirac semimetals with nontrivial topology.
A three-dimensional (3D) Dirac semimetal (SM) is the 3D analogue of graphene having linear energy dispersion around Fermi points. Owing to the nontrivial topology of electronic wave functions, the 3D Dirac SM shows nontrivial physical properties and hosts various exotic quantum states such as Weyl SMs and topological insulators under proper external conditions. There are several kinds of Dirac ...
متن کاملGapless layered three-dimensional fractional quantum Hall states
Using the parton construction, we build a three-dimensional 3D multilayer fractional quantum Hall state with average filling =1 /3 per layer that is qualitatively distinct from a stacking of weakly coupled Laughlin states. The state supports gapped charge e /3 fermionic quasiparticles that can propagate both within and between the layers, in contrast to the quasiparticles in a multilayer Laughl...
متن کاملInteracting Dirac liquid in three-dimensional semimetals
We study theoretically the properties of the interacting Dirac liquid, a novel three-dimensional many-body system which was recently experimentally realized and in which the electrons have a chiral linear relativistic dispersion and a mutual Coulomb interaction. We find that the “intrinsic” Dirac liquid, where the Fermi energy lies exactly at the nodes of the band dispersion, displays unusual F...
متن کاملTopological tuning in three-dimensional dirac semimetals.
We study with first-principles methods the interplay between bulk and surface Dirac fermions in three dimensional Dirac semimetals. By combining density functional theory with the coherent potential approximation, we reveal a topological phase transition in Na_{3}Bi_{1-x}Sb_{x} and Cd_{3}[As_{1-x}P_{x}]_{2} alloys, where the material goes from a Dirac semimetal to a trivial insulator upon chang...
متن کاملHelical liquid and the edge of quantum spin Hall systems.
The edge states of the recently proposed quantum spin Hall systems constitute a new symmetry class of one-dimensional liquids dubbed the "helical liquid," where the spin orientation is determined by the direction of electron motion. We prove a no-go theorem which states that a helical liquid with an odd number of components cannot be constructed in a purely 1D lattice system. In a helical liqui...
