Topological Coupling of Dislocations and Mag- Netization Vorticity in Spin Density Waves
نویسندگان
چکیده
The rich order parameter of Spin Density Waves allows for an unusual object of a complex topological nature: a half-integer dislocation combined with a semi-vortex of the staggered magnetization. It becomes energetically preferable to ordinary dislocation due to enhanced Coulomb interactions in the semiconducting regime. Generation of these objects changes the narrow band noise frequency.

Topological Dislocations and Mixed State of Charge Density Waves.
We discuss the possibility of the “mixed state” in incommensurate charge density waves with threedimensional order. The mixed state is created by applying an electric field perpendicular to the chains. This state consists of topological dislocations induced by the external field and is therefore similar to the mixed states of superfluids (type-II superconductors or liquid helium II). However, t...
متن کاملResponse of finite spin - S Heisenberg chains to local perturbations
We consider the properties of finite isotropic antiferromagnetic Heisenberg chains with S = 1/2, 1, 3/2 spins when a weak magnetic field is applied on a few sites, using White's density matrix renormalization group (DMRG) method. For the S = 1 chain there exists only one length scale in the system which determines the behavior of the one-and two-point correlation functions both around the local...

We theoretically demonstrate the interplay of uniform spin-orbit coupling and uniform Zeeman magnetic field on the topological properties of one-dimensional double well nano wire which is known as Su-Schrieffer-Heeger (SSH) model. The system in the absence of Zeeman magnetic field and presence of uniform spin-orbit coupling exhibits topologically trivial/non–trivial insulator depending on the h...

We analyze the phase diagram of a system of spin-1/2 Heisenberg antiferromagnetic chains interacting through a zigzag coupling, also called zigzag ladders. Using bosonization techniques we study how a spin-gap or more generally plateaux in mag-netization curves arise in different situations. While for coupled XXZ chains, one has to deal with a recently discovered chiral perturbation, the coupli...
متن کاملMulti- Q hexagonal spin density waves and dynamically generated spin-orbit coupling: Time-reversal invariant analog of the chiral spin density wave
We study hexagonal spin-channel (“triplet”) density waves with commensurate M-point propagation vectors. We first show that the three Q = M components of the singlet charge density and charge-current density waves can be mapped to multicomponent Q = 0 nonzero angular momentum order in three dimensions (3D) with cubic crystal symmetry. This one-to-one correspondence is exploited to define a symm...
