Critical properties of 1D spin-gapped fermions at the onset of magnetization

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/165843We develop an effective field theory for finding critical properties of 1D spin gapped fermions at the onset of magnetization. It is shown how the spin-charge interaction leads to a linear critical behavior and finite susceptibility for a wide range of models. We also discuss possible manifestations of spin-charge coupling in cold atomic gases.4 revtex pagesStrongly Correlated ElectronsCritical properties of 1D spin-gapped fermions at the onset of magnetizationtext
