Emerging nonequilibrium bound state in spin-current-local-spin scattering
Fatih Dogan, Lucian Covaci, Wonkee Kim +1
Magnetization reversal is a well-studied problem with obvious applicability in computer hard-drives. One can accomplish a magnetization reversal in at least one of two ways: applic…
Phase Fluctuations in High Temperature Superconductors
Wonkee Kim, Yan Chen, C. S. Ting
Within the phase fluctuation picture for the pseudogap state of a high- superconductor, we incorporate the phase fluctuations generated by the classical XY model with the Bo…
Electron and Spin Transport in the Presence of Complex Absorbing Potential
Fatih Dogan, Wonkee Kim, C. M. Blois +1
We examine the impact of a complex absorbing potential on electron transport, both in the continuum and on a lattice. This requires the use of non-Hermitian Hamiltonians; the requi…
Hall Conductivity in a Spin-Triplet Superconductor
Wonkee Kim, F. Marsiglio, C. S. Ting
We calculate the Hall conductivity for a spin-triplet superconductor, using a generalized pairing symmetry dependent on an arbitrary phase, $\vphi$. A promising candidate for such…
Impurity Scattering of Wave Packets on a Lattice
Wonkee Kim, L. Covaci, F. Marsiglio
Quantum transport in a lattice is distinct from its counterpart in continuum media. Even a free wave packet travels differently in a lattice than in the continuum. We describe quan…
Hidden Symmetries of Electronic Transport in a Disordered One-Dimensional Lattice
Wonkee Kim, L. Covaci, F. Marsiglio
Correlated, or extended, impurities play an important role in the transport properties of dirty metals. Here, we examine, in the framework of a tight-binding lattice, the transmiss…
