The Non-Dissipative Spin-Hall Conductivity and The Identification of the Conserved Current
D. Schmeltzer
The two dimensional Rashba Hamiltonian is investigated using the momentum representation.One finds that the SU(2) transformation which diagonalizes the Hamiltonian gives rise to no…
Topological spin current
D. Schmeltzer
We present an exact derivation for non-commuting coordinates induced by the SU(2) transformation used to diagonalize the spin-orbit hamiltonian in two dimension.As a result an exac…
Persistent spin currents induced by a spatially-dependent magnetic field in a spin-1/2 Heisenberg antiferromagnetic ring
D. Schmeltzer, A. Saxena, A. R. Bishop +1
We show that a spatially-dependent magnetic field can induce a persistent spin current in a spin-1/2 Heisenberg antiferromagnetic ring, proportional to the solid angle subtended by…
Transport through short quantum wires
D. Schmeltzer
At temperatures the collective excitations are negligible and the spectrum of the short wire is dominated by the ''zero modes'' particle e…
Transport in a spin polarized Luttinger liquid in the presence of a single impurity
Hsuan-Yeh Chang, D. Schmeltzer
The conductance for a single impurity in a one dimensional gas with electron-electron interaction and Zeeman splitting is considered. We f…
Hamiltonian Renormalization Groups
D. Schmeltzer
A Hamiltonian renormalization group is presented. Such a formulation is relevant for chiralic systems and more appropriate than the Lagrangian formalism. An application to 1D syste…
