Measurement of the Charm-Mixing Parameter y(CP) in D-0 -> K-S(0)Omega Decays at Belle
(American Physical Society, 2020-10-19)
We report the first measurement of the charm-mixing parameter y(CP) in D-0 decays to the CP-odd final state K-S(0 omega). The study uses the full Belle e(+)e(-) annihilation data sample of 976 fb(-1) taken at or near the ...
Magnetic Oscillations Induced by Phonons in Non-Magnetic Materials
(Nature, 2020-01-24)
The authors show that, similarly to electrons, in the presence of spin-orbit coupling, phonons can induce an effective magnetic oscillation even in non-magnetic materials, and therefore can act as an additional spin-flipping ...
Scaling density of axion strings
(APS, 2020-01-16)
In the QCD axion dark matter scenario with postinflationary Peccei-Quinn symmetry breaking, the number density of axions, and hence the dark matter density, depends on the length of string per unit volume at cosmic time ...
Irreducible background of gravitational waves from a cosmic defect network: update and comparison of numerical techniques
(APS, 2020-11-13)
Cosmological phase transitions in the early Universe may produce relics in the form of a network of cosmic defects. Independently of the order of a phase transition, topology of the defects, and their global or gauge nature, ...
Type I Abelian Higgs strings: evolution and Cosmic Microwave Background constraints
(APS, 2019-04-26)
We present results from the first simulations of networks of Type I Abelian Higgs cosmic strings to include both matter and radiation eras and cosmic microwave background (CMB) constraints. In Type I strings, the string ...
Fully anisotropic superconductivity with few Helmholtz Fermi-surface harmonics
(American Physical Society, 2020-10-09)
We present an alternative representation for the anisotropic Eliashberg equations of superconductivity, whose numerical solution yields an efficiency gain of several orders of magnitude with respect to the conventional ...
Contribution of defects to the spin relaxation in copper nanowires
(Americal Physical Society, 2013-03-18)
The contributions to the spin relaxation in copper (Cu) nanowires are quantified by carefully analyzing measurements of both charge and spin transport in lateral spin valves as a function of temperature and thickness. The ...
Coupled spin and electron-phonon interaction at the Tl/Si(111) surface from relativistic first-principles calculations
(American Physical Society, 2018-12-28)
We investigate the role played by the electron spin and the spin-orbit interaction in the exceptional electron-phonon coupling at the Tl/Si(111) surface. Our first-principles calculations demonstrate that the particular ...
Role of Ce substitution in the magneto-crystalline anisotropy of tetragonal ZrFe10Si2
(Elsevier, 2018-10-25)
We report the study of Zr1-xCexFe10Si2 (x = 0.0, 0.3 and 0.6) compounds, with tetragonal ThMn12 structure, by means of neutron diffraction and Mössbauer spectroscopy to understand the role of Ce in the increasing ...
Temperature dependence of spin diffusion length and spin Hall angle in Au and Pt
(Americal Physical Society, 2015-01-05)
We have studied the spin transport and the spin Hall effect as a function of temperature for platinum (Pt) and gold (Au) in lateral spin valve structures. First, by using the spin absorption technique, we extract the spin ...
