Higher Order Spin Noise Statistics
Fuxiang Li, Avadh Saxena, Darryl Smith +1
The optical spin noise spectroscopy (SNS) is a minimally invasive route towards obtaining dynamical information about electrons and atomic gases by measuring mesoscopic time-depend…
Spin noise of itinerant fermions
Simon Kos, Alexander V. Balatsky, Peter B. Littlewood +1
We develop a theory of spin noise spectroscopy of itinerant, noninteracting, spin-carrying fermions in different regimes of temperature and disorder. We use kinetic equations for t…
Detection of the spin character of Fe(001) surface states by scanning tunneling microscopy: A theoretical proposal
Athanasios N. Chantis, Darryl L. Smith, J. Fransson +1
We consider the magnetic structure on the Fe(001) surface and theoretically study the scanning tunneling spectroscopy using a spin-polarized tip (SP-STM). We show that minority-spi…
Theory of electrical spin-detection at a ferromagnet/semiconductor interface
Athanasios N. Chantis, Darryl L. Smith
We present a theoretical model that describes electrical spin-detection at a ferromagnet/semiconductor interface. We show that the sensitivity of the spin detector has strong bias…
Strain-Induced Conduction Band Spin Splitting in GaAs from First Principles Calculations
Athanasios N. Chantis, Manuel Cardona, Niels E. Christensen +5
We use a recently developed self-consistent GW approximation to present first principles calculations of the conduction band spin splitting in GaAs under [110] strain. The spin orb…
Reversal of spin polarization in Fe/GaAs (001) driven by resonant surface states: First-principles calculations
Athanasios N. Chantis, Kirill D. Belashchenko, Darryl L. Smith +3
A minority-spin resonant state at the Fe/GaAs(001) interface is predicted to reverse the spin polarization with voltage bias of electrons transmitted across this interface. Using a…
