Spin-charge separation in 1D fermions enables partially gapped deconfined quantum critical points between locally ordered phases, inferred via field theory and supported by numerical analysis of a microscopic model.
As already pointed out at the level of field theory, in or- der to find such transition to be continuous, both gaps have to vanish at the transition point
