Collapse of the hyperfine magnetic field at the Ru site in ferromagnetic rare earth intermetallics
D. Coffey, M. DeMarco, P. C. Ho +6
The Mössbauer Effect(ME) is frequently used to investigate magnetically ordered systems. One usually assumes that the magnetic order induces a hyperfine magnetic field, $B_{hyperfi…
Optical Conductivity in a Two-Band Superconductor: Pb
Nicolas Bock, Dermot Coffey
We demonstrate the effect of bandstructure on the superconducting properties of Pb by calculating the strong-coupling features in the optical conductivity, , due to the elect…
Adiabatic and Non-Adiabatic Contributions to the Free Energy from the Electron-Phonon Interaction for Na, K, Al, and Pb
N. Bock, D. Coffey, Duane C. Wallace
We calculate the adiabatic contributions to the free energy due to the electron--phonon interaction at intermediate temperatures, for the elemental me…
Non--Adiabatic Contributions to the Free Energy from the Electron--Phonon Interaction for Na, K, Al, and Pb
N. Bock, D. Coffey, Duane C. Wallace
We calculate the non--adiabatic contributions to the free energy of metals due to the electron--phonon interaction at intermediate temperatures, for f…
Magnetic Anisotropy in the Molecular Complex V15
N. P. Konstantinidis, D. Coffey
We apply degenerate perturbation theory to investigate the effects of magnetic anisotropy in the magnetic molecule V15. Magnetic anisotropy is introduced via Dzyaloshinskii-Moriya…
Evolution of Fermi Liquid Behavior with Doping in the Hubbard Model
Jungsoo Kim, D. Coffey
We calculate the single-particle Green's function for the tight-binding band structure, , with a function of chemical potential for square…
