Polarity effects in unsupported polar nanoribbons
(American Physical Society, 2013-05)
We analyze the characteristics of polarity in unsupported nanoribbons with zigzag edges, by a combination of analytic models, semiempirical Hartree-Fock simulations, and first-principles approach. We consider two materials ...
Large long-range F-F indirect spin-spin coupling constants. Prediction of measurable F-F couplings over a few nanometers
(American Chemical Society, 2004-05)
Large long-range indirect nuclear spin coupling constants are of great interest for quantum computers. But they are rarely observed and are usually considered very small, unless the coupled nuclear spins are proximate in ...
Unveiling the proton spin decomposition at a future electron-ion collider
(American Physical Society, 2015-11)
We present a detailed assessment of how well a future Electron-Ion Collider could constrain helicity parton distributions in the proton, and therefore unveil the role of the spin of quarks and gluons, as well as that of ...
Spin filtering in all-electrical three-terminal interferometers
(American Physical Society, 2017-02-15)
Unlike the two-terminal device, in which the time-reversal invariant spin-orbit interaction alone cannot polarize the spins, such a polarization can be generated when electrons from one source reservoir flow into two (or ...
Tuning the interfacial charge, orbital, and spin polarization properties in La0.67Sr0.33MnO3/La1-xSrxMnO3 bilayers
(American Institute of Physics, 2018-01)
The possibility of controlling the interfacial properties of artificial oxide heterostructures is still attracting researchers in the field of materials engineering. Here, we used surface sensitive techniques and high-resolution ...
Transformation of spin information into large electrical signals using carbon nanotubes
(Nature Publishing Group, 2007-01)
Spin electronics (spintronics) exploits the magnetic nature of electrons, and this principle is commercially applied in, for example, the spin valves of disk-drive read heads. There is currently widespread interest in ...
Dynamics of frequency-swept nuclear spin optical pumping in powdered diamond at low magnetic fields
(National Academy of Sciences, 2019-02)
A broad effort is underway to improve the sensitivity of NMR through the use of dynamic nuclear polarization. Nitrogen vacancy (NV) centers in diamond offer an appealing platform because these paramagnetic defects can be ...
Optimized phases for the acquisition of J-spectra in coupled spin systems for thermally and PHIP polarized molecules
(Academic Press Inc Elsevier Science, 2018-04)
We demonstrate that the relative phases in the refocusing pulses of multipulse sequences can compensate for pulse errors and off-resonant effects, which are commonly encountered in J-spectroscopy when CPMG is used for ...
Inclusive-jet and dijet production in polarized deep inelastic scattering
(American Physical Society, 2021-01-08)
We present the calculation for single-inclusive jet production in (longitudinally) polarized deep-inelastic lepton-nucleon scattering at next-to-next-to leading order (NNLO) accuracy, based on the projection-to-Born method. ...
Electroweak boson production at large transverse momentum in double polarized pp scattering at next-to-leading order accuracy
(American Physical Society, 2020-02)
We compute the next-to-leading order corrections to the cross section for the production of electroweak gauge bosons (Z, W± and γ∗) with large transverse momentum in double (longitudinally) polarized hadronic collisions. ...
