Spin depolarization in quantum wires polarized spontaneously in zero magnetic field
Spin depolarization in quantum wires polarized spontaneously in zero magnetic field
The conditions for a spontaneous spin polarization in a quantum wire positioned in a zero magnetic field are analyzed under weak population of one-dimensional (1D) subbands, which gives rise to the efficient quenching of the kinetic energy by the exchange energy of carriers. The critical linear concentration of carriers above …
