Universal spin dynamics in quantum wires
Abstract
We discuss the universal spin dynamics in quasionedimensional systems including the real spin in narrowgap semiconductors like InAs and InSb, the valley pseudospin in staggered singlelayer graphene, and the combination of real spin and valley pseudospin characterizing singlelayer transition metal dichalcogenides (TMDCs) such as MoS2, WS2, MoS2, and WSe2. All these systems can be described by the same Diraclike Hamiltonian. Spindependent observable effects in one of these systems thus have counterparts in each of the other systems. Effects discussed in more detail include equilibrium spin currents, currentinduced spin polarization (Edelstein effect), and spin currents generated via adiabatic spin pumping. Our work also suggests that a longdebated spindependent correction to the position operator in singleband models should be absent.

Unmodulated spin chains as universal quantum wires
We study a quantum state transfer between two qubits interacting with the ends of a quantum wire consisting of linearly arranged spins coupled by an excitation conserving, timeindependent Hamiltonian. We show that, if we control the coupling between the source and the destination qubits and the ends of the wire, the evolution of the system can lead to an almost perfect transfer even in the case in which all nearestneighbour couplings between the internal spins of the wire are equal. 
Kinetics of spin relaxation in quantum wires and channels: Boundary spin echo and formation of a persistent spin helix
In this paper we use a spin kinetic equation to study spinpolarization dynamics in onedimensional (1D) wires and 2D channels. The spin kinetic equation is valid in both diffusive and ballistic spin transport regimes and therefore is more general than the usual spin driftdiffusion equations. In particular, we demonstrate that in infinite 1D wires with Rashba spinorbit interaction the exponential spinrelaxation decay can be modulated by an oscillating function. In the case of spin relaxation in finite length 1D wires, it is shown that an initially homogeneous spin polarization spontaneously transforms into a persistent spin helix. We find that amore »
