Presenting a model for theoretical study of baryon masses, either in relativistic or nonrelativistic area, has always been of great importance and several suggestions have been proposed. On the other hand, taking into account the effects of hyperfine interactions leads to interesting results. In the present work, we first introduce the hyperfine interaction and the quark potential corresponding...
In most models, mesons consist of quark -antiquark pairs moving in a confining potential. However, it would be interesting to consider the effect of an extra residual interaction by introducing the quark particles which contain a dependent spin and isospin. In the Chiral constituent quark model, the hyperfine part of the potential is provided by the interaction of the Goldstone bosons, which ...
In this article nucleons are discussed based on constituent quark model. This model aims at studying the forces among three particles and the corresponding standard two-body potential contribution. The quark potential contains a hypercentral interaction. The confining potential is composed of four components,color charge, the oscillatory potential, the interaction quark and neutral gluon, and...
We study the hyperfine interaction between the nuclear spins and the electrons in a HgTe quantum well, which is the prime experimentally realized example of a two-dimensional topological insulator. The hyperfine interaction is a naturally present, internal source of broken time-reversal symmetry from the point of view of the electrons. The HgTe quantum well is described by the so-called Bernevi...
It has been proposed that valence-band holes can form robust spin qubits1–4 owing to their weaker hyperfine coupling compared with electrons5,6. However, it was demonstrated recently7–11 that the hole hyperfine interaction is not negligible, although a consistent picture of the mechanism controlling its magnitude is still lacking. Here we address this problem by measuring the hole hyperfine con...
The radical pair model has been successful in explaining behavioral characteristics of the geomagnetic compass believed to underlie the navigation capability of certain avian species. In this study, the spin dynamics of the radical pair model and decoherence therein are interpreted from a microscopic state transition point of view. This helps to elucidate the interplay between the hyperfine and...
Spin pumping is an interfacial spin current generation from the ferromagnetic layer to non-magnetic metal at its interface. The polarization of pumped $$\mathbf {J}_s \propto \mathbf {m}\times \dot{\mathbf {m}}$$ depends on dynamics magnetic moment {m}$$ . When materials are based light transition metals, mechanism behind transfer dominated by exchange interaction between localized d-electrons ...
