Spin-relaxation time in the impurity band of wurtzite semiconductors
(American Physical Society, 2017-09-18)
The spin-relaxation time for electrons in the impurity band of semiconductors with wurtzite crystal structure is determined. The effective Dresselhaus spin-orbit interaction Hamiltonian is taken as the source of the spin ...
Spin relaxation near the metal-insulator transition: Dominance of the Dresselhaus spin-orbit coupling
(American Physical Society, 2012-01)
We identify the Dresselhaus spin-orbit coupling as the source of the dominant spin-relaxation mechanism in the impurity band of a wide class of n-doped zinc blende semiconductors. The Dresselhaus hopping terms are derived ...
Nonmonotonic spin relaxation and decoherence in graphene quantum dots with spin-orbit interactions
(American Physical Society - APSCollege Park, 2014-03)
We investigate the spin relaxation and decoherence in a single-electron graphene quantum dot with Rashba and intrinsic spin-orbit interactions.We derive an effective spin-phonon Hamiltonian via the Schrieffer-Wolff ...
Relaxation mechanism for electron spin in the impurity band of n -doped semiconductors
(American Physical Society, 2007-12)
We propose a mechanism to describe spin relaxation in n -doped III-V semiconductors close to the Mott metal-insulator transition. Taking into account the spin-orbit interaction induced spin admixture in the hydrogenic donor ...
Spin-lattice relaxation of individual solid-state spins
(2018)
Understanding the effect of vibrations on the relaxation process of individual spins is crucial for implementing nanosystems for quantum information and quantum metrology applications. In this work, we present a theoretical ...

Dynamics and spatial distribution of water in Nafion 117 membrane investigated by NMR spin-spin relaxation
(Pergamon-Elsevier Science Ltd, 2018-05)
The dynamics and spatial distribution of water molecules in Nafion 117 membrane has been investigated by 1 H NMR. To this end, 1D and 2D spin-spin (T 2 ) relaxometry experiments were carried out as a function of the relative ...
Use of water spin-spin relaxation rate to probe the solvation of cyclodextrins in aqueous solutions

Ballistic spin resonance in multisubband quantum wires
(American Physical Society - APSCollege Park, 2014-03)
Ballistic spin resonance was experimentally observed in a quasi-one-dimensional wire by Frolov et al. [Nature (London) 458, 868 (2009)]. The spin resonance was generated by a combination of an external static magnetic field ...
