Periodic table for topological insulators and superconductors
Gapped phases of noninteracting fermions, with and without charge conservation and time-reversal symmetry, are classified using Bott periodicity. The symmetry and spatial dimension determines a general universality class, which corresponds to one of the 2 types of complex and 8 types of real Clifford algebras. The phases within a given class are further characterized by a topological invariant,...
متن کاملTopological Hermitian Cobordism
A decade ago, the authors [5] studied Real cobordismMR, anRO(Z/2)graded Z/2-equivariant spectrum discovered by Landweber [9], which is related to complex cobordismMU in the same way as Atiyah’s RealKtheory KR [1] does to K-theory. In particular, the authors computed the RO(Z/2)-graded coefficients of MR. A key step in that computation was the fact that MR is a complete Z/2-equivariant spectrum,...
متن کاملTopological transition in a non-Hermitian quantum walk.
We analyze a quantum walk on a bipartite one-dimensional lattice, in which the particle can decay whenever it visits one of the two sublattices. The corresponding non-Hermitian tight-binding problem with a complex potential for the decaying sites exhibits two different phases, distinguished by a winding number defined in terms of the Bloch eigenstates in the Brillouin zone. We find that the mea...
متن کاملPolynomial and non-polynomial solutions set for wave equation with using Lie point symmetries
This paper obtains the exact solutions of the wave equation as a second-order partial differential equation (PDE). We are going to calculate polynomial and non-polynomial exact solutions by using Lie point symmetry. We demonstrate the generation of such polynomial through the medium of the group theoretical properties of the equation. A generalized procedure for polynomial solution is pr...
