How many electrons are needed to flip a local spin?
Wonkee Kim, R. K. Teshima, F. Marsiglio
Considering the spin of a local magnetic atom as a quantum mechanical operator, we illustrate the dynamics of a local spin interacting with a ballistic electron represented by a wa…
Quantum Mechanics of Spin Transfer in Ferromagnetic Multilayers
Wonkee Kim, F. Marsiglio
We use a quantum mechanical treatment of a ballistic spin current to describe novel aspects of spin transfer to a ferromagnetic multilayer. We demonstrate quantum phenomena from sp…
Optical sum increase due to electron undressing
A. Knigavko, J. P. Carbotte, F. Marsiglio
For a system with a fixed number of electrons, the total optical sum is a constant, independent of many-body interactions, of impurity scattering and of temperature. For a single b…
Microwave Conductivity of a High Purity d-wave Superconductor
Wonkee Kim, F. Marsiglio, J. P. Carbotte
The cusp-like behavior of the microwave conductivity observed in clean ortho-II YBCuO at low temperature and low frequency is shown to be related directly to a…
Demonstration of a robust pseudogap in a three-dimensional correlated electronic system
R. J. Gooding, F. Marsiglio, S. Verga +1
We outline a partial-fractions decomposition method for determining the one-particle spectral function and single-particle density of states of a correlated electronic system on a…
