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…
