Integrability and chaos are two of the main concepts associated with nonlinear physical systems which have revolutionized our understanding of them. Highly stable exponentially localized solitons are often associated with many of the important integrable nonlinear systems while motions which are sensitively dependent on initial conditions are associated with chaotic systems. Besides dramaticall...

We show that the efficiency of manipulating electron spins in semiconductor quantum wells can be enhanced by tuning strain strengths. The combined effects of intrinsic and strain-induced spinorbit couplings vary for different quantum wells, which provide an alternative route to understand the experimental phenomena brought in by the strain. The contribution to the electron-dipole-spin-resonance...

Spin-dependent electronic transport through a quantum dot has been analyzed theoretically in the cotunneling regime by means of the second-order perturbation theory. The system is described by the impurity Anderson Hamiltonian with arbitrary Coulomb correlation parameter U . It is assumed that the dot level is intrinsically spin-split due to an effective molecular field exerted by a magnetic su...

Spintronics on flat surfaces has been studied over the years, and scenario is relatively well-known; however, there a lack of information when we consider non-flat surfaces. In this paper, are concerned about spin dynamics ferromagnetic model spherical surface. We use Schwinger bosonic formalism for describing thermodynamics operators in terms spinon operators. Opposite to two-dimensional model...
