Coupling of spin waves with charge- and spin-density excitations in spin-polarized quantum wells
نویسندگان
چکیده
The coupling of spin waves with chargeand spin-density waves is shown to be induced by a spin-dependent interaction in a quantum well, which is spin polarized by a dc magnetic field at an angle u to the symmetry axis. The mixing of the plasmonic and magnonic modes, which occurs for both intraand intersubband transitions, depends on the coupling constant of the spin-spin interaction, the tilt angle u , and the initial spin polarization z . @S0163-1829~99!08247-8#

Spin waves in a one-dimensional spinor bose gas.
We study a one-dimensional (iso)spin 1/2 Bose gas with repulsive delta-function interaction by the Bethe Ansatz method and discuss the excitations above the polarized ground state. In addition to phonons the system features spin waves with a quadratic dispersion. We compute analytically and numerically the effective mass of the spin wave and show that the spin transport is greatly suppressed in...

Stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar X groups; X =OH, SH, H, F, CN, and NO). There are meaningful correlations between changes of geometricalparameters and t...
متن کاملThe Thermodynamic Properties of Polarized Metallic Nanowire in the Presence of Magnetic Field
In this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. We have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. The spin-polarization parameter corresponding to the equilibrium state of ...
متن کاملHartree-Fock energy of a density wave in a spin polarized two-dimensional electron gas
We calculate the Hartree-Fock energy of a density-wave in a spin polarized twodimensional electron gas using a short-range repulsive interaction. We find that the stable ground state for a short-range potential is always either the paramagnetic state or the uniform ferromagnetic state. The energy of a density-wave state is, however, reduced by a factor proportional to (1 − ζ), where ζ is the po...
متن کاملSpin excitations of the spin-polarized electron gas in semimagnetic quantum wells.
Collective and single-particle spin-flip excitations of a two-dimensional electron gas in a semimagnetic Cd(1-x)Mn(x)Te quantum well are observed by resonant Raman scattering. Application of a magnetic field splits the spin subbands and a spin polarization is induced in the electron gas. Above 1 T the collective modes, which disperse with the in-plane wave vector, dominate the spectra. The loca...
