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…
Pairing Fluctuations in The Attractive Hubbard Model in the Atomic Limit
S. Verga, R. J. Gooding, F. Marsiglio
BCS theory accounts for the pairing instability in the weak coupling limit, but fails to describe pairing fluctuations above . One possibility for describing these fluctuation…
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…
