Spin Torque and its Relation to Spin Filtering
Wonkee Kim, F. Marsiglio
The spin torque exerted on a magnetic moment is a reaction to spin filtering when spin-polarized electrons interact with a thin ferromagnetic film. We show that, for certain condit…
Transport in vortex state of d-wave superconductors at zero temperature: Wiedemann-Franz violation
Wonkee Kim, F. Marsiglio, J. P. Carbotte
We show that the Wiedemann-Franz law is violated at zero temperature in the vortex state of a d-wave BCS superconductor with isotropic impurity scattering. We use a semiclassical a…
Self-Consistent Modification To The Electron Density Of States Due To Electron-Phonon Coupling In Metals
Fatih Dogan, Frank Marsiglio
The "standard" theory of a normal metal consists of an effective electron band which interacts with phonons and impurities. The effects due to the electron-phonon interaction are o…
Dynamics of a magnetic moment induced by a spin-polarized current
Wonkee Kim, F. Marsiglio
Effects of an incoming spin-polarized current on a magnetic moment are explored. We found that the spin torque occurs only when the incoming spin changes as a function of time insi…
Dynamic Hubbard Model: Effect of Finite Boson Frequency
F. Marsiglio, R. Teshima, J. E. Hirsch
Dynamic Hubbard models describe coupling of a boson degree of freedom to the on-site electronic double occupancy. In the limit of infinite boson frequency this coupling gives rise…
Low Temperature Thermal Conductivity of High Purity YBaCuO in the Vortex State
Wonkee Kim, F. Marsiglio, J. P. Carbotte
The low temperature thermal conductivity of a d-wave superconductor is considered for arbitrary strength of the impurity potential. A random distribution of vortices is included wi…
Wiedemann-Franz violation in the vortex state of a d-wave superconductor
Wonkee Kim, F. Marsiglio, J. P. Carbotte
We show that the Wiedemann-Franz law is violated in the vortex state of a d-wave superconductor at zero temperature. We use a semiclassical approach, which includes the Doppler shi…
Microscopic study of inhomogeneous superconductors
K. Tanaka, F Marsiglio
We study various inhomogeneity effects on superconductivity as due to quantum confinement, surfaces and impurities, using the self-consistent Bogoliubov-de Gennes formalism on the…
S-wave superconductivity near a surface
K. Tanaka, F. Marsiglio
We study the superconducting order parameter near a surface with the Bogoliubov-de Gennes formalism. For definiteness we use the attractive Hubbard model. Near a surface, the order…
