  • A non-adiabatically driven electron in a quantum wire with spin-orbit interaction [Elektronski vir]
    Čadež, Tilen, fizik ; Jefferson, John H. ; Ramšak, Anton
    An exact solution is derived for the wavefunction of an electron in a semiconductor quantum wire with spin-orbit interaction and driven by external time-dependent harmonic confining potential. The ... formalism allows analytical expressions for various quantities to be derived, for example spin and pseudo-spin rotations, energy and occupation probabilities for excited states. It is demonstrated how perfect spin and pseudo-spin flips can be achieved at high frequencies of the order of ▫$\omega$▫, the confining potential level spacing. By an appropriately chosen driving term, spin manipulation can be exactly performed far into the non-adiabatic regime. The implications for spin-polarized emission and spin-dependent transport are also discussed.
