Spin Dependent Thermoelectric Currents of Tunnel Junctions, Small Rings and Quantum Dots: Onsager Theory
K. Bennemann
Spin Currents in Tunnel Junctions for example induced by thermoelectric forces due to temperature and magnetization gradients etc. are analyzed. Using Onsager theory yields directl…
Photoinduced Phase Transitions
K. H. Bennemann
Optically induced ultrafast electronic excitations with sufficiently long lifetimes may cause strong effects on phase transitions like structural and nonmetal to metal ones. Exampl…
Magnetic Nanostructures
K. H. Bennemann
Characteristic results of magnetism in small particles and thin films are presented. As a consequence of the reduced atomic coordination in small clusters and thin films the electr…
Spin susceptibility in bilayered cuprates: resonant magnetic excitations
Ilya Eremin, Dirk K. Morr, Andrey V. Chubukov +1
We study the momentum and frequency dependence of the dynamical spin susceptibility in the superconducting state of bilayer cuprate superconductors. We show that there exists a res…
Charge Transport and Quantum Phase Transitions in Singlet Superconductor - Ferromagnet - Singlet Superconductor Junctions
Boris Kastening, Dirk K. Morr, Lambert Alff +1
We study the Josephson current, I_J, in a junction consisting of two s-wave superconductors that are separated by a ferromagnetic barrier possessing a magnetic and non-magnetic sca…
Two-dimensional Heisenberg antiferromagnet in a transverse field
P. J. Jensen, K. H. Bennemann, D. K. Morr +1
We investigate the magnetic reorientation in a two-dimensional anisotropic antiferromagnet due to a transverse magnetic field. Using a many-body Green's function approach, we show…
