Spin susceptibility of interacting electrons in one dimension: Luttinger liquid and lattice effects
H. Nélisse, C. Bourbonnais, H. Touchette +2
The temperature-dependent uniform magnetic susceptibility of interacting electrons in one dimension is calculated using several methods. At low temperature, the renormalization gro…
