Ballistic spin resonance in multisubband quantum wires
(American Physical Society, 2014-03-25)
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 ...
Quantum Monte Carlo study of the itinerant-localized model of strongly correlated electrons: spin-spin correlation functions
(American Physical Society, 2016-12-06)
We perform quantum Monte Carlo simulations of the itinerant-localized periodic Kondo-Heisenberg model for the underdoped cuprates to calculate the associated spin correlation functions. The strong electron correlations are ...
Chiral heat transport in driven quantum Hall and quantum spin Hall edge states
(American Physical Society, 2011-11)
We consider a model for an edge state of electronic systems in the quantum Hall regime with filling ν=1 and in the quantum spin Hall regime. In both cases, the system is in contact with two reservoirs by tunneling at point ...
Orbital and spin dynamics of intraband electrons in quantum rings driven by twisted light
(Optical Society of America, 2011-11)
We theoretically investigate the effect that twisted light has on the orbital and spin dynamics of electrons in quantum rings possessing sizable Rashba spin-orbit interaction. The system Hamiltonian for such a strongly ...
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 ...
Spin response of impurities in a quantum corral
(World Scientific, 2014-04)
In this work we investigate the dependence of spin observables, like the total spin alignment and the spin squeezing factor, for electrons confined inside an elliptic quantum corral and interacting with a pair of impurities ...
